11<H2>0. Prerequisites</H2>
12
13I will assume that you already have the Tcl/Tk package loaded on your computer. If this
14is not true, please see
15<A HREF="http://www.ncnr.nist.gov/~toby/tclpkgs.html">
16http://www.ncnr.nist.gov/~toby/tclpkgs.html
17</A> for installation instructions.
18Likewise, I will assume you have also loaded the appropriate GSAS release, if not see
19<A HREF="http://www.ncnr.nist.gov/~toby/unixgsas.html">
20http://www.ncnr.nist.gov/~toby/unixgsas.html
21</A> for installation instructions.
22
23<P>More information about EXPGUI, including information on how it
24can be customized, can be found on web pages <A HREF="http://www.ncnr.nist.gov/~toby/expgui/expgui.html">expgui.html</A>
25and <A HREF="http://www.ncnr.nist.gov/~toby/expgui/expgui_cfg.html">expgui_cfg.html</A>, found in the gsas/expgui/doc directory.

33<P>
34If you want to try the latest release (which may not have gotten
35a lot of testing, but probably has new bug fixes and capabilities) shift-click

46<H2>
472. EXPGUI Installation</H2>
48A few short steps are needed to load EXPGUI on your computer.
49<H4>
502.1 Create a directory and restore the files</H4>
51The EXPGUI scripts are set up to be run from a <B>subdirectory in the main GSAS
52directory</B>, by convention I assume the directory name <tt>expgui</tt>, but this is
53not required. Thus, if you have located the GSAS package in
54<TT>/usr/local/gsas</TT> (so that there is a directory
55<TT>/usr/local/gsas/exe</TT>, <TT>/usr/local/gsas/data</TT>, ...)
56I assume you will put
57these files in <TT>/usr/local/gsas/expgui</TT> but any subdirectory,
58such as <TT>/usr/local/gsas/tcl</TT> will work fine.
59Change the subsequent commands if GSAS is located somewhere
60other than <TT>/usr/local/gsas</TT>.
61
62<PRE>
63            cd    /usr/local/gsas
64            mkdir expgui
65            cd    expgui
66            gunzip <  [/path/]expgui.tar.gz  | tar xvf -
67</PRE>
68<P>When restoring the GSAS files from the tar file,
69note that <TT>[/path/]</TT> in the example above indicates the location
70where you downloaded the tar file in section 2, above.
71
72<H4>
732.2a Installing a shortcut to EXPGUI in .cshrc</H4>
74<P>To use EXPGUI, you probably need to create an easy way to access it.
75One way to do this is to add an alias to your ~/.cshrc file:
76<PRE>
77                cat >> ~/.cshrc
78                alias expgui "wish /usr/local/gsas/expgui/expgui"
79                ^D
80</PRE>
81<H4>
822.2b Installing EXPGUI in the path</H4>
83<P>
84Another way to simplify access to EXPGUI
85is to create a file which will execute the GUI script from
86a command in your system's path, for example <TT>/usr/bin</TT>.
87<PRE>
88                cat > /usr/bin/expgui
89                wish /usr/local/gsas/expgui/expgui
90                ^D
91                chmod +x /usr/bin/expgui
92</PRE>
93<H4>
942.2c Linking EXPGUI in the path</H4>
95<P>
96Another way to simplify access to EXPGUI
97is to create a link in your system's path to the GUI script.
98Note that you may need to modify the first line of
99<TT>/usr/local/gsas/expgui/expgui</TT>, if wish is located somewhere
100other than <TT>/usr/local/bin/wish</TT>.
101
102<PRE>
103                chmod +x /usr/local/gsas/expgui/expgui
104                ln -s /usr/local/gsas/expgui/expgui /usr/bin/expgui
105</PRE>
106
107<em>Note that in the above commands </em><TT>^D</TT><em> means control-D.</em>
108
109<H4>
1102.3 Installing TCLDUMP</H4>
111The TCLDUMP program should be located with all of the GSAS executable files, for example in /usr/local/gsas/exe/.
112<PRE>
113            cd    /usr/local/gsas/exe
114            gunzip <  [/path/]tcldump.tar.gz  | tar xvf -
115</PRE>
