26Intro to EXPGUI</h1></center>
27<P>
28<B>What is EXPGUI?</B><P>
29<blockquote>
30EXPGUI is a graphical user interface (GUI) editor for
31<A Href="http://www.ncnr.nist.gov/programs/crystallography/software/gsas.html">
32GSAS</A>
33experiment (.EXP) files and shell which allows all the other GSAS programs
34to be executed with a GUI.
35EXPGUI is not a replacement for the GSAS program EXPEDT.
36EXPGUI can do at best 10% of what
37EXPEDT can do -- but that 10% covers most of the
38actions that I use frequently (and that I could code without a major effort).
39</blockquote>

41<p><br><B>Is there documentation?</B>
42<blockquote>Some. There is:
43<UL>
44<LI>
45<A HREF="expgui.html">
46A User's Guide</A>, complete with lots of pictures

63Contributions of additional documents or improvements to existing
64documentation is greatly encouraged.

66
67<P><B>So what can EXPGUI do?</B>
68<blockquote>
69<dt>
70<i>Phase parameters</i>: EXPGUI can edit the cell and atomic parameters
71as well as the cell and atomic damping and refinement flags.</dt>
72
73<dt>
74<i>Histogram parameters</i>: Scale factor, background, diffractometer constants,
75phase fractions, profile terms can all be changed.</dt>
76
77<dt>
78<i>Least-Squares options:</i> control the number of cycles, the print options
79and F<sub>obs</sub> extraction parameters.</dt>
80
81<dt>
82<IMG SRC="note.gif">
83Creating new .EXP files and adding phases, histograms and atoms
84(EXPGUI version 1.17 and later).</dt>
85
86<dt>
87<IMG SRC="new.gif" HEIGHT=13 WIDTH=36>
88Editing and creating [hard] constraints on atomic parameters.
89Create and edit March-Dollase Preferred Orientation parameters.
90</dt>
91
92</blockquote>
93
94<p><br><B>So what can't EXPGUI do?</B>
95<blockquote>Much more than it can do. At this time, EXPGUI can't
96delete atoms or change their type.
97It cannot create or edit soft constraints
98or hard constraints, other than atomic constraints. It cannot be used on
99magnetic scattering parameters or on single-crystal histograms. It can't
100even change the profile function number. It also can't change the
101excluded data regions.
102<p>I hope to add some of these capabilities in the future, but EXPEDT is
103a huge program and it is unlikely that anyone will replace it any time
104soon. I will consider adding more functionality if requested and the job
105is reasonably tractable.
106</blockquote>
107
108<p><br><B>What type of computers will EXPGUI run on?</B>
109<blockquote>EXPGUI requires Tcl/Tk. While that is somewhat restrictive,
110it still means that EXPGUI will run on many more platforms than GSAS does.
111Most of the development has been done in LINUX with some testing on SGI
112and Windows-95 systems. I expect that EXPGUI will run on all platforms
113where GSAS does (except perhaps VMS).</blockquote>
114
115<p><br><B>Who is to blame for EXPGUI?</B>
116<blockquote>The initial version of the GUI part of EXPGUI was created by
117Jonathan Wasserman (thanks Jon!) <a href="http://www.ncnr.nist.gov/staff/toby/">Brian
118Toby</a> is irresponsible for the rest.</blockquote>
119
120<p><br><B>EXPGUI would be much more of use to me if....</B>
121<blockquote>Gee, you want to add some features... Great! You have all the
122EXPGUI sources and Tcl/Tk is free. Oh, you want me to do it. Well, I might
123get to it if you ask, particularly if you help.
124I am looking for good ideas on how to design GUI's
125for different aspects of experiment editing,
126with an attractive, intuitive and compact GUI.</blockquote>
127
128<p><br><B>Mailing List</B>
129<blockquote>If you would like to get news about EXPGUI, please send
130<a href="mailto:brian.toby@nist.gov?subject=EXPGUI Mailing List">Brian.Toby@NIST.GOV</a> e-mail and I
131will send you information about updates and bug fixes.
132Having lots of users might also help me justify this project to my
133employers.
