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/programs/crystallography/software/tclpkgs.html">
16http://www.ncnr.nist.gov/programs/crystallography/software/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/programs/crystallography/software/unixgsas.html">
20http://www.ncnr.nist.gov/programs/crystallography/software/unixgsas.html

23<P>More information about EXPGUI, including information on how it
24can be customized, can be found on web pages <A HREF="expgui.html">expgui.html</A>
25and <A HREF="expgui_cfg.html">expgui_cfg.html</A>, found in the gsas/expgui/doc directory.

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

38<P>
39Optionally download the TCLDUMP program to speed and enhance liveplot and the
40EXPTOOL program which allows EXPGUI to add phases, histograms and atoms
41to .EXP files.

602. EXPGUI Installation</H2>
61A few short steps are needed to load EXPGUI on your computer.
62<H4>
632.1 Create a directory and restore the files</H4>
64The EXPGUI scripts are set up to be run from a <B>subdirectory in the main GSAS
65directory</B>, by convention I assume the directory name <tt>expgui</tt>, but this is
66not required. Thus, if you have located the GSAS package in
67<TT>/usr/local/gsas</TT> (so that there is a directory
68<TT>/usr/local/gsas/exe</TT>, <TT>/usr/local/gsas/data</TT>, ...)
69I assume you will put
70these files in <TT>/usr/local/gsas/expgui</TT> but any subdirectory,
71such as <TT>/usr/local/gsas/tcl</TT> will work fine.
72Change the subsequent commands if GSAS is located somewhere
73other than <TT>/usr/local/gsas</TT>.
74
75<PRE>
76            cd    /usr/local/gsas
77            mkdir expgui
78            cd    expgui
79            gunzip <  [/path/]expgui.tar.gz  | tar xvf -
80</PRE>
81<P>When restoring the GSAS files from the tar file,
82note that <TT>[/path/]</TT> in the example above indicates the location
83where you downloaded the tar file in section 2, above.
84
85<H4>
862.2a Installing a shortcut to EXPGUI in .cshrc</H4>
87<P>To use EXPGUI, you probably need to create an easy way to access it.
88One way to do this is to add an alias to your ~/.cshrc file:
89<PRE>
90                cat >> ~/.cshrc
91                alias expgui "wish /usr/local/gsas/expgui/expgui"
92                ^D
93</PRE>
94<H4>
952.2b Installing EXPGUI in the path</H4>
96<P>
97Another way to simplify access to EXPGUI
98is to create a file which will execute the GUI script from
99a command in your system's path, for example <TT>/usr/bin</TT>.
100<PRE>
101                cat > /usr/bin/expgui
102                wish /usr/local/gsas/expgui/expgui
103                ^D
104                chmod +x /usr/bin/expgui
105</PRE>
106<H4>
1072.2c Linking EXPGUI in the path</H4>
108<P>
109Another way to simplify access to EXPGUI
110is to create a link in your system's path to the GUI script.
111Note that you may need to modify the first line of
112<TT>/usr/local/gsas/expgui/expgui</TT>, if wish is located somewhere
113other than <TT>/usr/local/bin/wish</TT>.
114
115<PRE>
116                chmod +x /usr/local/gsas/expgui/expgui
117                ln -s /usr/local/gsas/expgui/expgui /usr/bin/expgui
118</PRE>
119
120<em>Note that in the above commands </em><TT>^D</TT><em> means control-D.</em>
121
122<H4>
1232.3 Installing TCLDUMP</H4>
124The TCLDUMP program should be located with all of the GSAS executable files, for example in /usr/local/gsas/exe/.
125<PRE>
126            cd    /usr/local/gsas/exe
127            gunzip <  [/path/]tcldump.tar.gz  | tar xvf -
128</PRE>
129
130<H4>
1312.4 Installing EXPTOOL</H4>
132The EXPTOOL program should be located with all of the GSAS executable files,
133for example in /usr/local/gsas/exe/.
134<PRE>
135            cd    /usr/local/gsas/exe
136            gunzip <  [/path/]exptool.tar.gz  | tar xvf -
137</PRE>
