Likewise, I will assume you have also loaded the appropriate GSAS release, if not see http://www.ncnr.nist.gov/programs/crystallography/software/unixgsas.html for installation instructions. The current versions of EXPGUI must be used with GSAS versions released on or after April, 2001. EXPGUI v. 1.40 and later are not compatible with earlier Unix versions of GSAS -- as the file formats have changed.
More information about EXPGUI, including information on how it can be customized, can be found on web pages expgui.html and expgui_cfg.html, found in the gsas/expgui/doc directory.
If you want to try the latest release (which may not have gotten a lot of testing, but probably has new bug fixes and capabilities) shift-click on ftp://ftp.ncnr.nist.gov/pub/cryst/gsas/expgui_ALPHA.tar.gz P> If you have a version of GSAS from September 2001, or earlier and wish to set up dummy histograms from EXPEDT, you will need to update the EXPTOOL program using one of the following files:
cd /usr/local/gsas mkdir expgui cd expgui gunzip < [/path/]expgui.tar.gz | tar xvf -
When restoring the GSAS files from the tar file, note that [/path/] in the example above indicates the location where you downloaded the tar file in section 2, above.
/home/toby/mywish/wish /home/toby/mygsas/expgui/expguior whatever, you will likely want to create an easier command to type. Below are three ways to do this. Note that only one is needed. Do not use all three. Also, note that in the commands below, ^D means control-D.
To use EXPGUI, you probably need to create an easy way to access it. One way to do this is to add an alias to your ~/.cshrc file:
cat >> ~/.cshrc alias expgui "wish /usr/local/gsas/expgui/expgui" ^D
Another way to simplify access to EXPGUI is to create a file which will execute the GUI script from a command in your system's path, for example /usr/bin.
cat > /usr/bin/expgui wish /usr/local/gsas/expgui/expgui ^D chmod +x /usr/bin/expguiNote that this step (2.2b) is incompatible with the one below (2.2c).
Another way to simplify access to EXPGUI is to create a link in your system's path to the GUI script. Note that you may need to modify the first line of /usr/local/gsas/expgui/expgui, if wish is located somewhere other than /usr/local/bin/wish.
chmod +x /usr/local/gsas/expgui/expgui ln -s /usr/local/gsas/expgui/expgui /usr/bin/expguiNote that this step (2.2c) is incompatible with the one above (2.2b). H3> 2.3 Installing EXPTOOL If being upgraded, the EXPTOOL program should be placed in the directory with the GSAS executable files, for example in /usr/local/gsas/exe/.
cd /usr/local/gsas/exe gunzip < [/path/]exptool.tar.gz | tar xvf -
|[tammy@beryl tammy]$ wish||(note a window is created)|
|% set tcl_version|
|8.0||(8.0 is the Tcl/Tk version number. EXPGUI requires 8.0 or higher)|
|% package require BLT|
|2.4||(2.4 is the BLT package version number. EXPGUI requires 2.3 or higher. If you get "can't find package BLT" then BLT is not installed [properly] on your system)|
|% blt::graph .g|
|.g||(nothing happens. You should not get an error message here.)|
|% pack .g||(now a graph is displayed)|
|% Blt_ZoomStack .g||(if error message: invalid command name "Blt_ZoomStack" appears there is a problem with your BLT installation, see below.)|
