Notice: A
new streamlined version is available now for testing (Bear2007.CAB).
All programs should be operational. Please report any problems you encounter.
The Berkeley Texture Package BEARTEX provides a set of over 30
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
and electron diffraction data.
BEARTEX requires Windows 95, Windows 98, Windows 2000, Windows
NT or XP and a 386, 486 or Pentium processor. It appears to be working on VISTA
though it has not been tested extensively. 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 and a HP laser
printer for output is suggested. We apologize that the current HELP file is not
up to date.
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.
- HEXF Prepares a file with angle positions for an equal
area hexagonal measuring grid
- CORR Corrects pole figure data for background and
defocusing
- FICO Calculates a theoretical defocusing curve, also for
thin films
- HEXR Prepares a file for rotated angle positions (use
with CORR)
- SYPF Manipulates synchrotron and neutron diffraction data
- ABXX Corrects and processes data for strongly textured
samples (e.g. epitaxial thin films)
- THET Calculates d from 2q and 2q from d for various
wavelengths
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
- MIMA Evaluates if OD is determinable from a given set of
complete or incomplete pole figures
- WIMV Calculates OD from a set of complete or incomplete
pole figures
- PCAL Calculates any pole figure from the OD
- ICAL Calculates inverse pole figures from the OD
- SMOO Smoothes and sharpens the OD. Useful if OD is noisy
("filtering")
- COMP Intensity integration within a sphere of texture
component positions
- TENS Calculates physical tensor properties of textured
polycrystals
- TENX Averages tensor properties of polyphase materials
- VELO Determines p, s1 and s2 wave surfaces from stiffness
tensor
(b) Single orientation branch (only simplest operations)
- STPF Calculates pole figures from standard Gaussians at
single orientations.
- STOD Calculates OD from standard Gaussians at single
orientations.
- INOR Calculates OD-like representation of individual
orientation data
- F2AN F2 statistics.
- MIOR Misorientations.
- ODFW Adds weights to individual orientations based on
texture densities.
- TRAN Orientation variants during phase transformations.
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.
- CLMN Calculates harmonic coefficients from the OD
- HIOR Calculates coefficients from individual orientations
- HODF Compiles ODF from coefficients
- HAPF Calculates pole figures from coefficients
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.
- CHBI Converts the standard binary OD file YOD into ASCII
formats (Berkeley format, MAUD format and Standard
format)
- CMAU Converts OD output from MAUD into Beartex binary
format
- CHPF Converts pole figures. The user must provide
subroutine for individual changes
- CHWI Converts xpx to WIMV input. Used, e.g. for
synchrotron data processing
- CSEC Calculates various OD sections in different angle
conventions and sample symmetries
- CHST Converts OD from standard listing (STD) into binary
format (Y??)
- MACU Converts Macintosh/Unix data (different convention
for linefeed)
- HKLX Converts (for cubic crystals only) Euler angles to
(hkl)[uvw) and vice versa
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.
- CONT Contour plot in polar coordinates of OD-sections or
pole figures.
- PODF plots ODF sections in Cartesian coordinates.
- PING Produces color images of pole figures that can be
saved as bmp files.
- XYCO Contour plots of OD sections or pole figures in
rectangular format.
- PTXX Plot of individual orientations (or components).
Preferred Output HP Laser Jet.

BEARTEX can be downloaded from the web by clicking on the link
below. Follow the procedure:
- Download Bear2000.CAB
to your PC computer. With Explorer double click and it
will guide you. With Netscape or Mozilla right click on
the link, then "Save Target As...". The current
version is 2.3, updated 11.20.2003.
- Bear2000.CAB is a package of all files that can be
unzipped with Winzip (double click on it on the PC).
Create a directory (e.g. C:\ProgramFiles\Beartex) and
install it there. Do not use this directory for your data
processing.
- Copy the file "temp.new" to
"temp.pif" (this should not be necessary any
more)
- Start the program by clicking on Bear2000.exe. Place a
shortcut on the desktop.
- This will allow you to run the programs in a demo mode.
All windows are accessible and WIMV can be
executed. If you decide to purchase Beartex, you will
need to supply a serial number (in HELP REGISTER), then
you will get a registration number to run all programs
upon purchasing the package.
- A new version that is not yet fully tested is also
available Bear2007.CAB.
It has several new programs and improved features, as
well as a new Help file and manual (Beartex.doc). Please
contact us if you find problems with it. This new Beartex
needs a new registration number that will be provided
free of charge if you have purchased Beartex within the
last two years. Otherwise the upgrade (and two years of
service) can be obtained at half the cost of the original
purchase.

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.
We are working on a new version of Beartex: Bear2008, mainly with improved
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):
