- Small improvements in the Data Digitizing window.
- Small improvements in the Data Worksheet to speed the processing of large files (cursor movement, avoiding to plot data for too large files, avoiding unnecessary data validation).
Version 4.0.2, released on 21/01/2012, after intensive testing on recent field data for a new publication.
Version 4.0.1, released on 17/01/2012, with resolution of a small but ennoying problem in the Solutions management that appeared during the last modifications.
Version 4.0.0, released on 15/01/2012, with important new features.
- Computation of standard deviations (1 s) for horizontal stress directions (SHmax/Shmin) and stress regime index (R'). This is an important new technical feature which will be detailed soon in a specific User Guide.
- All the processing options have been regrouped in a new Processing Option dialog window, accessible under Menu/Data or by right clicking on the Subset Manager. Except for the Weighting option, all the other options have been removed from the related processing tab.
- The color management in the Graphic Option dialog windows has been improved.
- An insert for displaying the horizontal stress directions and stress regime has been added as overlay on the relevant stereograms. Its visibility and display mode is controlled in the Graphic Option dialog windows. It allows to copy the stress symbols independently from the figures with the stereogram. Several display mode are available: as usual stress arrows, as focal mechanisms, as SHmax, Shmin or SHmax/Shmin, and as rose diagrams.
- In the Solution Management, Solutions record also the current processing parameters. These are restored when a solution is selected and applied, in order to reprocess the data using the same paramters as the ones used to obtain the recorded solution.
- In the legend of the figures with stereograms, "sigma" is replaced by the greek "s" for the stress axes (a user request).
- Many other small improvemnts and bugs fixed.
Version 3.0.0, released on 02/04/2011, specially for the EGU General Assembly, Vienna, April 4-8 2011. A new version with major improvements and additions concerning mainly the Processing Worksheet, bringing among others a Solution management system witch was long waited by the users.
- Implementation of a Solution management system, for recording and applying stress tensor solutions.
A solution contains the 4 parameters of the reduced stress tensor, and the list of subsets used. It is designated by a name, qualified by the method used (PBT, Dieder or ROptim) and a comment text can be added. When applying a solution, it first applies the subset selection recoded, then selects the appropriate method, and applies it to the selection. If the method is Rotational Optimisation, the parameters of the recorded stress tensor are restored before the stress tensor is applied.
- A drop-down list has been added in the Processing worksheet, just above the Subset management tress view. It allows creating new solutions or loading existing ones. Three buttons allow applying a solution or recording the parameter of a solution.
- A Solution Management window has been added to view and modify the solution list. It is accessible via Menu / Data / Manage Solutions.
- Solutions Reports can be generated directly from the Solution Management window, for single solutions or for the entire solution list. Solutions are reported in 3 different ways. First, in the form of a text file with tab-separated solution parameters arranged in the form of a table. They can be copied and pasted into an excel worksheet. The content of the text file is saved also to the clipboard which can be pasted directly in a text file, an excel sheet or a word document. The last - but not the least - kind of report is a word document which is automatically generated with a table containing most relevant figures (stereonets, regression curves and Mohr diagrams).
- The menu items have been revised and rationalized for more clarity.
- The subset minor index which has been selected for rejecting data is displayed in the Subset tree view with a red background.
- The speed of scrolling in the data table has been significantly improved for long files and is no more sensitive to the number of data.
- In the Roses tab, a new view has been added, which allows to calculate and display the apparent dip of planes along a section plane.
- In the Data worksheet, some icons have been added on the command bar.
Version 2.2.9, posted on 10/02/2011. Important update :
Solution of some problems, new rose diagrams and addition of a Query function as suggested by some users.
- Data table in Processing worksheet: solution of problems when highlighting the cursor and corresponding row.
- Data table in Data worksheet: solution of problems in data format conversion and data validation.
In particular, for faults or focal mechanism with slip lines, changing the line format into Rake (line format 4) was causing a problem when the slip sense is defined as unknown (X), the Rake being angle undefined in that case.
The Rake angle contains information on both the slip line orientation in the plane and the slip direction. If one of these data is missing, the Rake cannot be defined.
It results in a loose of information on the slip line orientation during conversion into Rake format for fault planes with slip lines and undetermined sense of movement. To avoid this, conversion of line format for those data into Rake is now forbidden and is converted into Pitch angle/Pitch direction instead (line format 3).
- Rose diagrams
- Improvement of graphic display
- Addition of a new view (Fault-slip data: Roses only) with 3 new rose diagrams: rose of dip-directions for planes, pitch angle for slip lines and rake directions for slip lines with determined slip sense.
The Dip-direction diagram reflects both the orientation of the fault plane and its direction of dip. The dip-direction of a plane is the normal to ist strike orientation, pointing in the direction of dip.
The Pitch diagram reflects the obliquity of the line in the plane, knowing that the pitch is close to 0 for pure strike-slip faults and to 90 for pure dip-slip faults. The Pitch angle is measured in the fault plane as the angle between the slip line and the trace of the horizontal on the plane.
The Rake diagram reflects also the slip line obliquity as it is based on pitch angle, but includes also information on the slip sense. It contains therefore only fault data with slip line and known sense of movement.
According to Aki and Richards (1980), an earthquake focal plane or a slickensided fault plane is entirely determined by 3 angles: the azimuth of the horizontal trace of the fault (strike), the dip angle of the fault and the rake angle of the line. The latter is based on the angle of the slip vector in the fault plane with reference to the strike (pitch angle), calculated in a way to reflect also the slip sense (0,+180 for reverse faults and -180,0 for normal faults), with Rake = 0 for pure left-lateral strike-slip (SD) faults, 90 for pure reverse dip-slip (IX) faults, +/-180 for pure right-lateral strike-slip (XD) faults and -90 for pure dip-slip normal (NX) faults. The intermediate Rake angles reflect oblique-slip movements, with 0 to 90 for Inverse-sinistral (IS), 90 to 180 for Inverse-dextral (ID), 0 to -90 for Normal-Sinistral (NS), -90 to -180 for Normal-Dextral (ND).
Aki, K., Richards, P.G., 1980. Quantitative Seismology, Freeman and Co., New York. Second Edition, University Science, 2002, 700p.
- Change/Assess Subset Index dialog box in the Processing sheet
- Addition of a Query function for searching text elements (word(s), phrase) in the Id and Comment fields Processing sheet data table and assessing minor Subset Index according to the query result.
- The default setting of the application range of the actions Changing/Assessing the Subset Index has been modified to All Subsets. This implies that actions will be performed on all subsets by default.
However, if the view mode for the data table is defined to display only the data corresponding to the selected subsets (option Menu / View / Show Non selected subsets is unchecked), the default setting for the application range is set to Selected subsets, in order to avoid modifying the hidden data.
- When all subsets are selected, a warning message appears. This message can be desactivated by replying "Cancel" on the message dialog box or in the Processing pane of the General Options by unchecking option "Allow warning messages for applying Subset Index changes".
- For most panels of the dialog box, a button "Desactivate all" has been added. It rests the corresponding combo-boxes to neutral position (X = No Change).
Version 2.2.8, posted on 3/01/2011. Minor update
- The statistics for linear data has been improved (details in the guide book in preparation)
- A problem appeared sometimes during the installation of version 2.2.7. This version 2.2.8 has been recompiled in the same way as the preceding versions. Version 2.2.6 is posted again in case this problem persists
Version 2.2.7, posted on 6/12/2010. Minor update
- Tensor parameters were not transferred correctly from PBT module to RO (Rotational Optimisation) module this has been fixed.
- Separation of data in function of kinematic type has been revised.
- A new color palette has been added to the node edition windows of the Subset manager for fault data classified in function of their kinematic type.
Version 2.2.6, posted on 20/11/2010. Important update
- An important number of small issues have been fixed, of which several reported by users that are thanked for their contribution.
- The code has been further optimised for more fluidity in the processing.
Version 2.2.4, posted on 27/09/2010. Minor update
- When an old file in .dat format is open in Win-Tensor, the 'File Save' function is turned into 'File Save As' proposing a .wtd extension. This is to prevent the lost of information not compatible with the old .dat version when saving the file.
- Some floating dialog windows have been downsized in order to optimize the screen management.
Version 2.2.3, posted on 27/08/2010. Minor update
- A mistake was introduced when optimizing the program for fast processing of large files. It caused incorrect display of the girdle and cluster distribution in module Statistics. It is now solved.
Version 2.2.0, posted on 26/07/2010. Win-Tensor appears in a more mature way after the fast developments that have been done recently.
- The main functions have been optimized and improved for a better clarity and stability.
- The statistics of orientation data has been formalized together with the preparation of a corresponding User Guide for the Statistics Module. The synthetic test file (Cluser-Girdle.wtd) used for demonstration in the User Guide is also posted.
- The Dieder Method has been expanded in order to take into account also neoformed shear fractures by the definition of a new specific counting grid.
- Two small stereonets have been added on the Dieder panel, to display for the selected data the individual counting grid (above) and the differential counting frid (below).
- Function F5 in the Rotational Optimization has been revised and expanded to take into account the shear fractures, with and without apparent sense of displacement. A specific User Guid has been prepared, together with an excel file for testing openly the formula used.
- Win-Tensor has been tested for larges file (up to 1200 data) and optimized for faster computation.
- Enjoy ... and send my your feedback !
Version 2.1.4, posted on 6/06/2010. Small adjustments and improved weighting factor.
- New: weighting of the data during processing can be one in 3 different ways: proportional, (* weight), square (* weight^2), exponential (* 10^weight).
The square weighting is more appropiate for the analysis of fault-slip data when the weight factor is proportional to the side of the exposed fault surface and the exponential function can be used for focal mechanism data when the weight factor corresponds to the magnitude of the earthquake.
The default value for this option can be defined in the general default properties (Menu/Tools/Option) and it can be changed interactively in the Graphics properties, next to the check box relative to the weighting option.
Version 2.1.0, posted on 16/02/2010. Major step foreward towards completion of the program. Brand new fonctionalities, improvements and bugs corrected. Important new functions for the Processing Sheet and new data types in the Data Sheet. Download it now.:
- New function: Rotation panel - Allows to perform 2 successive rotation of data and stress tensors. Included is the definition of a reference plane that can be used to monitor the rotations. Contains all the common fonctionalities (data hot-traking, display controls, windows resizing...).
- Various improvements and corrections of the exisiting functions
- Increased stability during stress tensor rotation
- Reworking of the limiting angle during subset separation in Statistics and PBT panels, together with cone angle display on stereogram.
- Faults planes without slip lines but with apparent sense of displacement given by a displaced reference plane can now be used in the rotational optimization function.
Version 2.0.1, posted on 11/02/2010. Major step foreward towards completion of the program. Brand new fonctionalities, improvements and bugs corrected. Important new functions for the Processing Sheet and new data types in the Data Sheet. Download it now.:
- New function: Statistics panel - Provides an analysis of the distribution of planar data (poles of planes) and line data. It allows also separating the data into subsets. Details will be given in the User Guide.
- New function: PBT Analysis panel - Offers a new way to estimate the stress tensor and separate data, using the well known technique based on the analysis of kinematic p, b, and t axes. Details will be given in the User Guide.
- Floating Data Separation & Dieder Processing / Tensor Optimisation control -For the Right Dihedron and Rotational Optimisation panels, the lower control frame which controls the tensor optimisation and data separation could be hidden when the data table was expanded upwards. Now, instead they are transferred to floating Dialog boxes whey the data table begin to overlap them.
- All stereograms with active data hot tracking - For all stereograms, moving the mouse with the left button pressed allows to recognise and highlight the displayed data and to highlight the data line in the data table. Conversely, the displayed data are highlighted on the graphics when scrolling on the data table in the processing sheet.
- Improved stability during tensor optimisation - Increase of calculation precision by using 3 decimals for the variables containing the orientation of the strass axis orientation.
- Subset Index change function - Development of function Change/Assess Subset Index in Menu/Data. Up to 10 different ways to define the subset index of selected data in function of various paramters. Details will be given in the User Guide.
- Subset Index selection function - New option in Menu/Data : Select Minor Index. This function applies to the tree view of the Subset Manager where it allows to check/unchek multiple check boxes corresponding to the nodes of the minor subsets. Details will be given in the User Guide.
- Fault separation function - New option in Menu/Data : Separate Fault-slip Data. This function is only available for the Rotational Optimisation panel as it works using the resolved shear stress data. Details will be given in the User Guide.
- New data type 9 - Current direction determined from bedding plane and oblique current plane.
- New data type 10 - Horizontal stress axes from s1, s2, s3 and stress ratio R. This last data type is useful for calculating horizontal stress directions SHmax and Shmin using the methodology described in Lund and Townend (2007), for updating existing results without recalculating them. It allows also to create a file with the resulting stress tensors then display their orientations and inclinaisons using the Rose diagrams.
Version 1.4.23, posted on 01/02/2009. Small bugs in Lateral Projection fixed.
Version 1.4.22, posted on 20/01/2009. The program was used intensively for processing both geological field data and earthquake focal mechanisms. This allowed to highlight - and solve - a new series of issues. New small but practical functionalities were added and adaptations made. Important new features are:
- Labels - Some labels have been changed in Rotational Optimisation: SD (for Slip Deviation) is converted into a (misfit angle) and FA (Friction Angle) into f .
In addition, Win-Tensor provides now the standard deviation for the misfit angle: s(a) and for the current optimisation function F as their maximal value max(a) and max(F).
- Picture format - In Right Dihedron and Rotational Optimisation, the format of the pictures on which are drawn the stereonet is adapted when only the stereonet appear. The format of the picture is changed into a square, which is more convenient for integrating the pictures in a table.
- Initial data number - The previous system for determining the initial number of data when updating the data selection was not satisfactory.
This parameter is used in the course of the data selection procedure when progressively eliminating the misfit data.
It is also important for the Quality Ranking as it appears in the ratio of data used in the final inversion relative to the initial number of data in the raw subset.
In version 1.4.12 and above, the initial data number is re-assessed for each change in the selection of the major (or primary) Subset Index nodes (the integer part of the Subset Index) in the Subset Manager tree-view.
The initial data number is defined as the total number of data belonging to all minor subsets attached to the selected major subset.
If several major subsets are selected, the total number of data belonging to all these subsets is considered.
Only valid data for the current module is considered (e.g. faults with slip line but without slip sense are not considered in Right Dihedron and bedding or foliation planes and unknown type of fracture in both Right Dihedron and Rotational Optimisation).
In the data separation procedure, it is assumed that the initial data subsets that have to be separated are the major (or primary) subsets. For working efficiently, the arrangement of data into subsets using the Subset Index has to be made accordingly in the Data Worksheet, prior starting the processing.
- Initial data number for focal mechanisms - When working with focal mechanisms in Rotational Optimisation, the initial data number, determined as above, is divided by 2.
Effectively, for each focal mechanism in the database, two focal planes are generated and loaded in the data table of the Processing Worksheet.
At the end of the processing, only one focal plane (the actual slip plane) should remain and the other (the auxiliary plane), left aside in another minor subset.
- Lateral projection - We implemented something apparently strange: a lateral projection for the stereonet in Rotational Optimisation.
Unsual stereonet projection are -by convention- a projection of the trace of planes, poles or lines from an horizontal plane, onto a lower (or upper) hemisphere.
Why not projecting them from a vertical plane onto a "lateral" hemisphere away from the observer?
That vertical plane can be chosen orthogonal to the horizontal projection of the intermediate stress axis s2 (SHmax direction for normal faulting tensors and Shmin direction for thrust faulting tensors).
In Win-Tensor, this is simulated by performing two successive rotations of all data before projecting them.
This is particularly interesting for normal faulting or thrust faulting stress regimes as the fault planes will be seen with s1 axis bisecting the related conjugated fault systems (if any).
Otherwise, in the classical projection, it is for strike-slip regimes that this can be seen.
The use of this type projection should be avoided for strike-slip stress systems as it does not improve the readability of the stereogram and can lead to rather strange results.
For activating this function, check the box "Lateral Projection" in the Rotational Optimisation tab of the Graphic Option window.
As all this might not be obvious, save the following sample data files and try it:
Version 1.4.19, posted on 06/08/2008. New: Exact calculation of horizontal stress directions using the methodology described in Lund and Townend, (2007). Geophys. J. Int., doi: 10.1111/j.1365-246X.2007.03468.x.
Version 1.4.15, posted on 27/04/2008. New: Implementation of a semi-automatic data separation procedure for the Rotational Optimisation module as it was already for the Right Dihedron module. New features:
- Frame Tensor Optimisation & Data Separation for interactive data separation and stress tensor optimisation.
- For both the Right Dihedron and Rotational Optimisation module: possibility to sort the results in the data table in function of the values of the relevant parameters (Counting Deviation CD for Right Dihedron, Slip deviation SD or Optimisation Function for Rotational Optimisation).
- After tensor calculation, the data for which the value of these parameters are higher than the threshold are set in black.
- Sorting activation/desactivation using command: Menu/View/Sort data according to Results (checked: sorted, unchecked: unsorted).
- Changing sorting order using command: Menu/View/Sort order Ascending (checked: Ascending, unchecked: Descending).
- These three new parameters are stored automatically.
Version 1.4.13, posted on 12/04/2008. New: Discrimination between different subsets in the same stereogram by using different colours.
Version 1.4.12, posted on 08/04/2008. New: Discrimination between different subsets in the same stereogram by using different colours.
- Following the request of some users, subsets can now be discriminated using colors.
- This has requested the definition of Properties for the Data Subsets (Subset Color and Subset label).
- The Subset properties are defined using the TreeView of the Data Subset Management in the Processing Worksheet.
- The Subset properties are recorded at the end of the related data file. This causes some problems when loading on Win-Tensor version 1.4.8 or below, a file generated by Win-Tensor 1.4.12 or above.
- A subset legend can be placed in the stereograms in function of the space available.
- Detailed information on the Data Subset Manager are available in the User Guides or can be downloaded directly
Version 1.4.8, posted on 19/02/2008. Several practical improvements !
- Graphic Options now include the control of graphic colors.
- Option Weighting has been unified for all modules (changing in in one module will change it for all modules).
- Legend of stress axis has been added to stereonets of Right Dieder and Rotational Optimisation modules.
- In the data table of the DataSheet module, it is now possible to change interactively the Data Type of each data row. Changing the Type will cause an adaptation of the Input Data values in function of the Compiled Data values from the previous Data Type. Like that, e.g. changing the type of focal mechanism (Types 5, 6, 7) into another type of focal mechanism will not affect the compiled data but well the input data. This copmpletes the existing possibility of changing the Data Format which is operated following the same principle, on the basis of the Compiled Data from the previous Data Format.
- Column headers for the data grid in the Processing sheet has been finalised.
- For Data Type 5 (Focal Mechanism), the extensional mechanisms are indicated by 'E' instead of 'N' and compressional ones, by 'C' instaed of 'I' or 'R'. It is still possible however to type letters 'N' and 'I' or 'R', but these will be converted respectively into 'E' and 'C'.
- Solution of remaining issues in the DataSheet module.
Version 1.4.1, posted on 03/01/2008. Major step in the development, program name changed into Win-Tensor !
- Program name changed into Win-Tensor (executable file Win_Tensor.exe) due to confilct with another program for crystallography registred under the name WinTensorTM.
- Graphic Options in the Processing sheet have been transferred to a specific window, and further developed. They can be accesses via Menu/Graphics/Options or by right-clicking on a graphic picture and selection Options.
- Rose diagrams are now available in the Roses Panel of the Processing Sheet. They are assembled, together with small stereonets, in series of 6 graphics, grouped in 5 different views.
- small improvements and solution of issues.

- Results of calculations can be displayed, recorded on file or copy to the clipboard.
- Processing of focal mechanisms is automated with separation between movement and auxiliary planes according to the value of the misfit function.
- Control of valid data for the Rotational Optimisation function before optimisation.
- Files can be opened simply by dropping them on the main window of WinTensor.
- Numerous small improvements and solution of remaining issues.
Version 1.3.149, posted on 2007/03/23.
- Implementation of a quality ranking scheme for the Dieder method.
- Optimisation and stability of R ratio in optimisation mode 1 is performed using the full range of stress regimes (R' values texted between 0 and 3) instead of testing R values (between 0 and 1) for a particular stress regime.
- Regression curves also display axis stability in rotational optimisation.
- Small improvement and solution of minor issues.
Version 1.3.142, posted on 2007/01/10.
- Addition of an Undo - Redo function for the text boxes of the Data Worksheet.
- Small improvement and solution of minor issues.
Version 1.3.139, posted on 2006/12/08. Small adjustments
Version 1.3.136, posted on 2006/12/05. Data highlighted on graphics interactively using the mouse.
- The structural data displayed on graphics are highlighted when approaching the mouse pointer. Similarly, the corresponding row in the data table in also highlighted (for Right Dieder and Rotational Optimisation stereograms as for Mohr diagrams). To highlight data on a graphic : press the left button of the mouse (a yellow cross appear) and move the pointer close to an object by keeping the left button pressed. When the button is released, the yellow cross disappear.
- The data are highlighted on graphics when scrolling on the data table in the processing sheet.
- Selected data can be removed from a subset by right clic on the mouse (minor index set to ",9")
- Many small features were improved or completed.
Version 1.3.129, posted on 2006/11/21: optimisation curves and Mohr diagrams
- Addition of regression curves showing the value of the optimising function versus rotation angle or R value for the rotational optimisation.
- Implementation of Mohr diagram.
- All graphics can now be copied to BMP files or to the clipboard.
- The tensor parameters are recorded on a Tensor Solution file ".ten" after each new processing, as in the Dos version. A button "Load" was placed on the Rotational Optimisation sheet to load the existing tensor solutions from the .ten file, select one of them and use its parameters for a new processing.
- Use of the command line to open directly the file by double-clicking on ".wtd" or ".ten" files.
Version 1.3.121, posted on 2006/10/18: digitalisation of focal mechanisms
- New option to digitize focal mechanism data from P and T kinematic axes on a scanned stereogram.
