30A new mechanism for installing GSAS & EXPGUI is now recommended. See
31<A HREF="https://subversion.xray.aps.anl.gov/trac/EXPGUI/wiki/InstallLinux">
32this link</a>. If this method is used, EXPGUI or a python script can
33be used to update GSAS & EXPGUI quickly and easily. The information
34below is all obsolete.
35Also, GSAS updates for the Silicon Graphics have not been produced for
36many years.

39Note that root access is not required to load this GSAS/EXPGUI package.
40You may choose to do this work as root, so that the files may be installed
41a central location (such as <tt>/usr/local</tt>).
42
43<H2>1. Prerequisites</H2>
44
45Installation of GSAS & EXPGUI requires X windows, which is loaded with
46the operating system on virtually all Linux and SGI systems.
47It also requires only the shared libraries typically found on standard
48install configurations (tell me if I am wrong).
49The Linux version is compiled with g77 v2.96 on a Redhat 7.1 machine.
50It should be compatible with most modern versions of Linux.
51The SGI version has been compiled with f77 on a SGI running IRIX 6.5. It should
52be compatible with most recent versions of IRIX.
53<IMG SRC="new.gif" HEIGHT=13 WIDTH=36 alt="New!">
54This GSAS & EXPGUI is now distributed with a version of Tcl/Tk,
55so installation of Tcl/Tk is no longer a prerequisite.

1354. Installing a shortcut to EXPGUI</H2>
136While it is possible to invoke EXPGUI by typing
137<FONT FACE="COURIER"><PRE>
138    /usr/local/gsas/tcltk84+ /usr/local/gsas/expgui/expgui

144(etc.) this would get old fast. Rather, you will likely want to
145create an easier command to type.
146Below are three ways to do this. Note that only one is needed. Do not use all
147three. You could also create a startbar or desktop icon that can be clicked
148to start EXPGUI.
149The way this is done depends on how your system is set up and cannot
150be described here.
151
152<em>Note that in the commands below, it is assumed that
153GSAS has been installed in <tt>/myprogs/gsas</tt>.

157
158<UL><H4>
1594.1 Installing an alias for EXPGUI</H4>
160<P>
161One way to create a easy way to invoke EXPGUI is to add an alias to your
162default shell.
163First, determine what shell you are using. Type
164<PRE>
165    echo $SHELL
166</PRE>
167
168The response will likely be something like /usr/bin/bash (the bash shell) or
169/usr/bin/tcsh (the tcsh shell).
170<P>
171<DL>
172<DT>If you use tcsh or csh:
173<DD>to add an alias to your ~/.cshrc file, type these commands
174(change <tt>/myprogs</tt> as needed):
175<FONT FACE="COURIER"><PRE>
176         cat >> ~/.cshrc
177         alias expgui "/myprogs/gsas/tcltk84+ /myprogs/gsas/expgui/expgui"
178         ^D
179</PRE></FONT>
180
181<DT>If you use bash:
182<DD>to add an alias to your ~/.bash_profile, type these commands
183(change <tt>/myprogs</tt> as needed):
184<FONT FACE="COURIER"><PRE>
185         cat >> ~/.bash_profile
186         alias expgui="/myprogs/gsas/tcltk84+ /myprogs/gsas/expgui/expgui"
187         ^D
188</PRE></FONT>
189</DL>

191<H4>
1924.2 Installing EXPGUI in the path</H4>
193<P>
194Another way to simplify access to EXPGUI
195is to create a file that will invoke the GUI script.
196The file must be placed in a directory in your path and
197flagged as executable. You can examine the directories in your path by typing:
198<PRE>
199    echo $PATH
200</PRE>
201Also, check to see that you do not alreay have expgui command in your path
202by typing:
203<PRE>
204    which expgui
205</PRE>
206You should get a response "expgui not found in...". A response of
207<tt>/usr/bin/expgui</tt> tells you there is already a shortcut to expgui
208in that location. Either replace it or choose a name other than expgui.
209<P>
210The commands to create this executable file will be:
211<FONT FACE="COURIER"><PRE>
212        cat > /usr/bin/expgui
213        /myprogs/gsas/tcltk84+ /myprogs/gsas/expgui/expgui
214        ^D
215        chmod +x /usr/bin/expgui
216</PRE></FONT>
217(change <tt>/myprogs</tt> and <tt>/usr/bin</tt> as needed).
218
219<I>Note that this step (4.2) is incompatible with the one below (4.3).</I>
220<H4>
2214.3 Linking EXPGUI into the path</H4>
222<P>
223Another way to simplify access to EXPGUI
224is to create a link in your system's path to the GUI script.
225First, you will need to edit the 3rd line in the EXPGUI script from
226<PRE>
227      exec wish "$0" "$@"
228</PRE>
229to
230<PRE>
231      exec /myprogs/gsas/tcltk84+ "$0" "$@"
232</PRE>
233(change <tt>/myprogs</tt> as needed).
234Then you will create a link using:
235                ln -s /myprogs/gsas/expgui/expgui /usr/bin/expgui
236</PRE></FONT>
237<I>Note that this step (4.3) is incompatible with the one above (4.2).</I>

241<H2>Updating to a new GSAS release</H2>
242<DL><DL>
243It is quite common that Bob Von Dreele will release an update to the
244GSAS programs more frequently than the combination gsas+expgui
245is updated. It is possible to update only the
246GSAS software.
247To determine the date of the GSAS package release,
248run a GSAS program, such as EXPEDT or SPACEGRP and note the
249date where it says "Distributed on ..."
250To update,
251first determine where you have installed the GSAS/EXPGUI software
252(<tt>/myprogs</tt> in the previous example).
253You will want to install the GSAS distribution to the <tt>gsas</tt> 
254subdirectory in that location.
255Then download the latest GSAS release from CCP14:

271</DL>
272<P>Select and download the appropriate gsaskit.tar.gz (making sure that the
273listing date is significantly later than the distribution date
274you currently have).
275Then use commands like this:
276
277<P><DL>
278<DT>SGI, use command
279<DD><PRE>
280cd /myprogs/gsas

283<DD><PRE>
284cd /myprogs/gsas
285tar xvzf /tmp/gsaskit.tar.gz</PRE>
286</DL>
287<P>
288Finally, check that GSAS has indeed been updated by
289again running a GSAS program, such as EXPEDT or SPACEGRP and noting the
290date where it says "Distributed on ..."
291</DL></DL>
292
293<H2>Updating to a new EXPGUI release</H2>
294<DL><DL>
295It is also common that new features will be added to EXPGUI or
296bug fixes will be made without an update to the
297combination gsas+expgui
298package.
299The absolute latest release (which may not have gotten
300a lot of testing)
301is distributed as
302<A HREF="ftp://ftp.ncnr.nist.gov/pub/cryst/gsas/expgui_ALPHA.tar.gz">
303ftp://ftp.ncnr.nist.gov/pub/cryst/gsas/expgui_ALPHA.tar.gz</A>.
304You can find the number of the latest alpha release by looking at file
305<A Href="http://www.ncnr.nist.gov/xtal/software/expgui/alpha/wishlist.html">
306http://www.ncnr.nist.gov/xtal/software/expgui/alpha/wishlist.html</A>
307<P>
308To update,
309first determine where you have installed the GSAS/EXPGUI software
310(<tt>/myprogs</tt> in the previous example).
311You will want to install the GSAS distribution to the <tt>gsas/expgui</tt> 
312subdirectory in that location.
313Second, note the EXPGUI package date, by
314using the Help/About menu command in EXPGUI.
315You then want to download this file:

350RPMs for GSAS/EXPGUI are not being updated</H2>
351I am no longer preparing an RPM distribution for GSAS & EXPGUI. This
352is because it was getting increasingly hard to find RPM distributions
353for Tcl/Tk and BLT. If one has to install & build these packages from
354source code, then one must also override the RPM package tracking
355system to install the GSAS & EXPGUI RPM.
356The current method, which includes the entire Tcl/Tk package is
357easier to deal with.
358<P>
359<h2>The Tcl/Tk Starkit</H2>
360<P>
361The GSAS-EXPGUI distribution now includes a single file version of the
362entire Tcl/Tk package, as well as a graphics package for Tcl/Tk, called
363BLT, that is used extensively within EXPGUI. The inclusion of this file
364within the package simplifies installation considerably.
365This file,
366<tt>tcltk84+</tt>, contains many other Tcl/Tk packages (that are
367not used within EXPGUI), but may be of value for use with other applications.

370Using other versions of Tcl/Tk</H2>
371If you have another version of Tcl/Tk installed on your computer,
