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. BEARTEX is free to download and use.

A new version of BEARTEX, Bear2020noreg, for 64-bit Windows 10 can be downloaded  . You need to run Beartex as "Administrator". The interactive help for older versions is not working for Windows 10 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 file in an empty directory (e.g. BEARTEX), and expand it then into this directory. Do not use this directory for your data.

For 64bit Windows 10 you need to copy files sysinfo.ocx, comdlg32.ocx, grid32.ocx and comctl32.ocx from the BEARTEX directory into the directory C:\Windows\syswow64. Then activate the 4 files in the command (cmd) window as administrator (choose "administrator" with right-click): type "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. ). 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.

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.

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
