Win-Tensor Release notes Release 1.4.x - 02/01/2008 --------------------------------- The Tensor programme was originally developed in QuickBasic for MsDos (Dos Tensor). The first version was officially presented at the EUG VII Strasbourg in 1993. Since then it was regularly upgraded till December 2001 (version 4.33). This last version includes the Quality Ranking Scheme according to the World Stress Map 2000 release. In order to follow the technological progress, a new Visual Basic 6 for Windows version of the same program (Win-Tensor) started to be developed in 2001. The database module was completed in early 2005 and tested in summer 2005. Development of the processing module is in progress, and the present version is released for testing and evaluation. Version 1.4 has already most of the fonctionalities of both TENSORD and TENSORP modules of the TENSOR for DOS programme. When developing the Win-Tensor, we paid a special attention to keep the same general layout, working principles, functionalities and user-friendly character as in the TENSOR for DOS programme. Those characteristics have been highly appreciated in the Dos version and contributed to make it so popular. In the new version for Windows, we tried hard to maintain this, while offering most of the advantages of the Windows operating system and adding new functionalities. A user which is accustomed to work with the TENSORD module will find the same functionalities in the Data Worksheet of the Win-Tensor programme, and will be able to use in most cases the same keyboard keys as in the older version. The main differences, improvements and developments offered by the Win-Tensor are the following: 1. The Windows version is designed as a Multiple Interface Document (MDI) application, while the Dos version was a Single Interface Document (SID) application. MDI applications contain a main (or parent window) and all other windows are opened as child windows within the main window. Closing or minimizing the main window will affect automatically all the child windows. The child windows can be arranged in different ways within the parent window, the default setting being the Cascade arrangement. 2. Different file formats. In adaptation to the .dat format of the older Tensor for DOS version, the Win-Tensor read and write data files as .txt, .csv and .xls formats. These three new formats allow recording more information?s on the orientation data. It is advised to save data in .txt or .csv formats for storing the data entered using the Windows version. As the functions for paleostress determination are not yet available in the Windows version the data should be saved also as .dat file to allow their use in TERSORP module. This will however cause some lost of qualitative information. 3. Use of several different data format in a single data file. In the DOS version, the format for entering the data in the database is defined for each file, for the all the data included in that file. Now, a Default format is still defined for the entire data sheet, but there is an additional possibility to define the data format for each data line. 4. Conversion of data format. The format for recording the data is no more fixed once the data have been entered. It is now possible to change the format of any existing data line, just by modifying the format definition. This can be done individually for each data, for a group of selected data of for the whole file. 5. The functionalities of the TensorD module for managing the database are now present on a Data Worksheet. It contains four frames, displaying respectively the site characteristics, the data grid, stereonets and the description of the active data row. The site characteristics, the data stereonets and the data description frames can be selectively hidden in order to provide more space for the data grid. 6. Data grid. The data are entered and displayed in a Data Grid with Copy/Paste and Drag/Drop functions that allow easy exchange of data with other worksheets. 7. In the Dos version, the displaying of the data could be done only in the TENSORP module, and not in the database module. Now, data are displayed immediately on stereonets while the orientation data are entered or modified. A first stereonet displays the data of the active data row, even if the data row is not yet complete. A second (and slightly larger) stereonet displays together all the data present in the data grid, or only the data selected if a range of data has been selected. 8. Printing and saving graphics. A major drawback of the Dos version was the difficulty of printing the graphics displayed. This could be done indirectly by copying it on the clipboard by using the Print-Screen key, then pasting it into a graphic program like Paint and finally by saving it as a graphic file format. Now, the graphics can be directly copied on the clipboard, or saved as .bmp files. 9. Digitalisation of data directly from scanned stereonets. A fully new function has been developed ? and to our best knowledge this is probably the first time ? which allow digitising orientation data from any existing stereographic display. An electronic copy of a figure can be loaded as .BMP or .JPG file or simply pasted. After definition of the coordinates of the stereonet (center and radius of the external circle), the orientation data can be digitized from the data plotted on the stereonet. 10. The fault-slip data can now be grouped in 10 major subsets and 10 minor subsets for each of the major ones. 11. The processing sheet assemble in one single window: - a data table with only the compiled fault-slip data and columns with the different indexes (only the Working Index is editable); - a tree view for selecting the data subsets; - a series of panels with the mains tools of the processing sheet 12. Within the Right Dihedron and the Rotational Optimisation panels, the control units, the results and the graphics are all presented side by side. 13. The processing and separation of data with the Right Dihedron function is now more automatized, with a possibility to go both forward and backwards in the process (using less or more data). This offers the possibility to test different steps in the separation of data, then to choose the best results interactively. 14. The Windows version of the Rotational Optimisation method is fully developed and is linked to display panels for regression curves and Mohr diagrams. 15. Rose diagrams for a large variety of data are available and grouped into 5 different "views". The Win-Tensor program version 1.4 (executable file Win_Tensor-14.exe is contained in the Windows Installer Package Win_Tensor-14.msi. This allow installing the program on the most recent operating systems, including Windows XP and Vista.
