Introduction to BEARTEX

The Berkeley Texture Package BEARTEX provides a set of over 35 programs running under the Windows environment to analyze preferred orientation in polycrystalline materials. The system is designed for users who are not texture theoreticians but need quantitative texture data for their applications. BEARTEX is independent of x-ray hardware and many programs can also be used to process neutron, synchrotron X-ray and electron diffraction data.

The classical BEARTEX requires Windows 95, Windows 98, Windows 2000, Windows NT or XP and a 386, 486 or Pentium processor. A math coprocessor is almost a necessity as most of the programs are very numerically intensive. VGA (640 X 480) or Super VGA (800 X 600 or 1024 X 768) color graphics is highly recommended. A new version is available for Windows XP (Bear2012.CAB). All programs should be operational. Please report any problems you encounter. This version, including HELP files, can be used on Windows 7, Windows 8 and Macintosh platforms using a "virtual machine" (see below).

An new version of BEARTEX version for 64-bit Windows Vista Windows 7 and Windows 8  is also posted in two versions which should be almost identical, Bear2014x.CAB and Bear2015x.zip . You need to run Beartex as "Administrator". The interactive help is not working for Windows 7 and 8 and you need to consult the file Beartex.rtf for information about the programs. Also currently dates of output files may not be correctly updated.

Be sure you have the CAB file in an empty directory (e.g. BEARTEX), and expand it then into this directory.

For 64bit Windows 8 you need to copy files sysinfo.ocx, comdlg32.ocx, grid32.ocx and comctl32.ocx into the directory C:\Windows\syswow64 and then activating them in the command (cmd) window as administrator (choose "administrator" with right-click): regsvr32 c:\windows\syswow64\sysinfo.ocx etc.

The  Macintosh (OS X 10.4, 10.5) processors may still require a virtual machine, which can be downloaded for free from (e.g. http://www.virtualbox.org/wiki/Downloads). Once the virtual machine is set up, Windows XP needs to be installed in order to run BEARTEX. The new version Bear2014x also works with Windows XP, however you need to replace the function olepro32.dll in the Beartex installation directory with the older version. The older version can be downloaded from here (olepro32-old.dll) and after installation renaming it to olepro32.dll.

Note that a new version of Bear2014x.exe has a date of 7/3/2014. In the previous version the file smoo2.exe has been missing. Use this version (or simply add the missing file to your directory). Apologies.

BEARTEX  is constantly updated and the latest version is posted on the web. Basic features are described in J. Appl. Cryst. 31, 262-269 (1998).

Programs are divided into 5 groups:

1) ACQUIRE are a set of programs related to acquisition of x-ray diffraction data. They may require some special subroutines to interface with your goniometer hardware. Also included are programs for data corrections, both for bulk samples and for thin films.

2) PROCESS is the central core of BEARTEX. It contains programs to calculate ODs and do various operations with the OD.

The programs can be formally divided into two branches, but can be used in any sensible combination: (a) Conventional texture analysis, (b) Single orientation analysis and modeling by standard functions.

(a) Conventional branch

(b) Single orientation branch (only simplest operations)

3) HARMONIC contains some programs using the series expansion method, mainly related to the treatment of individual orientation data, e.g. from SEM-EBSP measurements.

4) CONVERT includes programs to change file formats, angle conventions, orientations. The file format for pole figure input and graphic representations is the "new" Berkeley format.

5) DISPLAY contains programs for graphic display of texture data on monitor (in colors with possibility to prepare PCX file, contour plots on HP Laser Jet printer or on dot matrix printers.

How to order BEARTEX

The package can be obtained from the University of California at a nominal cost with revenues used to maintain and improve the software. Current price for a single license is still $ 1000 for Universities and $ 2000 for Industry and Research Laboratories. A site license can be obtained for the price of two single licenses. Price includes shipping, technical help and free updates for 2 years. Payment is by check or money order in US $. Sorry, Credit Cards can not be accepted at this time. Checks are to be made out to "Regents of the University of California" or you can use Bank transfer (details are supplied with invoice). If you are interested contact wenk@berkeley.edu or write to Rudy Wenk, Dept. Earth and Planetary Science, University at California, Berkeley CA 94720.


Preview: Simple Shear Movie

Beartex has graphics capabilities such as the possibility to prepare movies of pole figure evolution. Download the example of halite deformed in simple shear to very large strains illustrating constant tumbling of texture patterns. In this 100 pole figure the shear plane is horizontal and shear is dextral. Symbol size is proportional to individual grain deformation. You can view the AVI file e.g. with VLC Media Player (freeware): Halite100.AVI
