    38 <H2>0. A one-step process for Linux</H2>
    39 Many Linux releases incorporate a package-loading program called RPM.
    40 The RPM package file loads, <A Href="http://www.ncnr.nist.gov/programs/crystallography/software/gsas.html">GSAS</A> and
    41 <A Href="http://www.ncnr.nist.gov/xtal/software/expgui">
    42 EXPGUI</A>, as well as checks that your Linux system has been configured
    43 properly to run these programs (for example, has Tcl/Tk and BLT loaded).
    44 The most recent <font face="courier">GSAS-EXPGUI-yyyy.mm.dd-x.i386.rpm</font>
    45 file
    46 (where yyyy, mm & dd are year, month and day)

     35Note that root access is not required to load this GSAS/EXPGUI package.

    6939<H2>1. Prerequisites</H2>
    7040
    71 I will assume that you already have the Tcl/Tk package loaded on your computer. If this
    72 is not true, please see
    73 <A HREF="http://www.ncnr.nist.gov/programs/crystallography/software/tclpkgs.html">
    74 http://www.ncnr.nist.gov/programs/crystallography/software/tclpkgs.html
    75 </A> for installation instructions. Please note that EXPGUI seems to run very
    76 slowly in Tcl/Tk version 8.1, but OK in 8.0 and 8.2.
    77 Also see <a href="#testtcltk">below</a> on how to test if Tcl/Tk is properly
    78 installed.
    79 <P>
    80 Likewise, I will assume you have also loaded the appropriate GSAS release, if not see
    81 <A HREF="http://www.ncnr.nist.gov/programs/crystallography/software/unixgsas.html">
    82 http://www.ncnr.nist.gov/programs/crystallography/software/unixgsas.html
    83 </A> for installation instructions.  The current versions of EXPGUI must be
    84 used with GSAS versions released on or after April, 2001.
    85 <I>EXPGUI v. 1.40 and later are not compatible with earlier Unix versions of
    86 GSAS -- as the file formats have changed.</I>
    87 
    88 <P>More information about EXPGUI, including information on how it
    89 can be customized, can be found on web pages <A HREF="expgui.html">expgui.html</A>
    90 and <A HREF="expgui_cfg.html">expgui_cfg.html</A>, found in the gsas/expgui/doc directory.
    91 
     41Installation of GSAS & EXPGUI requires X windows, which is loaded with
     42the operating system on virtually all Linux and SGI systems.
     43It also requires only the shared libraries typically found on standard
     44install configurations (tell me if I am wrong).
     45The Linux version is compiled with g77 v2.96 on a Redhat 7.1 machine.
     46It should be compatible with most modern versions of Linux.
     47The SGI version has been compiled with f77 on a SGI running IRIX 6.5. It should
     48be compatible with most recent versions of IRIX.

     50This GSAS & EXPGUI is now distributed with a version of Tcl/Tk,
     51so installation of Tcl/Tk is no longer a prerequisite.

    105 3. EXPGUI Installation</H2>
    106 A few short steps are needed to load EXPGUI on your computer.
    107 <H3>
    108 2.1 Create a directory and restore the files</H3>
    109 The EXPGUI scripts are set up to be run from a <B>subdirectory in the main GSAS
    110 directory</B>, by convention I assume the directory name
    111 <font face="courier">expgui</font>, but this is
    112 not required. Thus, if you have located the GSAS package in
    113 <FONT FACE="COURIER">/usr/local/gsas</FONT> (so that there is a directory
    114 <FONT FACE="COURIER">/usr/local/gsas/exe</FONT>, <FONT FACE="COURIER">/usr/local/gsas/data</FONT>, ...)
    115 I assume you will put
    116 these files in <FONT FACE="COURIER">/usr/local/gsas/expgui</FONT> but any subdirectory,
    117 such as <FONT FACE="COURIER">/usr/local/gsas/tcl</FONT> will work fine.
    118 Change the subsequent commands if GSAS is located somewhere
    119 other than <FONT FACE="COURIER">/usr/local/gsas</FONT>.
    120 
    121 <FONT FACE="COURIER"><PRE>
    122             cd    /usr/local/gsas
    123             mkdir expgui
    124             cd    expgui
    125             gunzip <  [/path/]expgui.tar.gz  | tar xvf -
    126 </PRE></FONT>
    127 <P>When restoring the GSAS files from the tar file,
    128 note that <FONT FACE="COURIER">[/path/]</FONT> in the example above indicates the location
    129 where you downloaded the tar file in section 2, above.

    133132While it is possible to invoke EXPGUI by typing
    134133<FONT FACE="COURIER"><PRE>
    135                 wish /usr/local/gsas/expgui/expgui

     140(etc.) this would get old fast. Rather, you will likely want to
     141create an easier command to type.
    142142Below are three ways to do this. Note that only one is needed. Do not use all
    143 three.
    144 
    145 <em>Also, note that in the commands below,
     143three. You could also create a startbar or desktop icon that can be clicked
     144to start EXPGUI.
     145The way this is done depends on how your system is set up and cannot
     146be described here.

    150 2.2a Installing a shortcut to EXPGUI in .cshrc</H4>
    151 <P>To use EXPGUI, you probably need to create an easy way to access it.
    152 One way to do this is to add an alias to your ~/.cshrc file:
     1554.1 Installing an alias for EXPGUI</H4>
     156<P>
     157One way to create a easy way to invoke EXPGUI is to add an alias to your
     158default shell.
     159First, determine what shell you are using. Type
     160<PRE>
     161    echo $SHELL
     162</PRE>
     163
     164The response will likely be something like /usr/bin/bash (the bash shell) or

    160189<P>
    161190Another way to simplify access to EXPGUI
    162 is to create a file which will execute the GUI script from
    163 a command in your system's path, for example <FONT FACE="COURIER">/usr/bin</FONT>.
     191is to create a file that will invoke the GUI script.
     192The file must be placed in a directory in your path and
     193flagged as executable. You can examine the directories in your path by typing:
     194<PRE>
     195    echo $PATH
     196</PRE>
     197Also, check to see that you do not alreay have expgui command in your path
     198by typing:
     199<PRE>
     200    which expgui
     201</PRE>
     202You should get a response "expgui not found in...". A response of
     203<tt>/usr/bin/expgui</tt> tells you there is already a shortcut to expgui
     204in that location. Either replace it or choose a name other than expgui.
     205<P>
     206The commands to create this executable file will be:

    173218<P>
    174219Another way to simplify access to EXPGUI
    175 is to create a link in your system's path to the GUI script.
    176 Note that you may need to modify the first line of

     240GSAS programs more frequently than the combination gsas+expgui
     241is updated. It is possible to update only the
     242GSAS software.
     243To determine the date of the GSAS package release,
     244run a GSAS program, such as EXPEDT or SPACEGRP and note the
     245date where it says "Distributed on ..."
     246To update,
     247first determine where you have installed the GSAS/EXPGUI software
     248(<tt>/myprogs</tt> in the previous example).
     249You will want to install the GSAS distribution to the <tt>gsas</tt>
     250subdirectory in that location.
     251Then download the latest GSAS release from CCP14:

     347RPMs for GSAS/EXPGUI are not being updated</H2>
     348I am no longer preparing an RPM distribution for GSAS & EXPGUI. This
     349is because it was getting increasingly hard to find RPM distributions
     350for Tcl/Tk and BLT. If one has to install & build these packages from
     351source code, then one must also override the RPM package tracking
     352system to install the GSAS & EXPGUI RPM.
     353The current method, which includes the entire Tcl/Tk package is
     354easier to deal with.
     355<P>
     356<h2>The Tcl/Tk Starkit</H2>
     357<P>
     358The GSAS-EXPGUI distribution now includes a single file version of the
     359entire Tcl/Tk package, as well as a graphics package for Tcl/Tk, called
     360BLT, that is used extensively within EXPGUI. The inclusion of this file
     361within the package simplifies installation considerably.
     362This file,
     363<tt>tcltk84+</tt>, contains many other Tcl/Tk packages (that are
     364not used within EXPGUI), but may be of value for use with other applications.
