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>
40
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
47<LI>
48<A HREF="expgui_Win_readme.html">
49Installation notes for Windows</A>
50<LI>
51<A HREF="expgui_Unix_readme.html">
52Installation notes for UNIX</A>
53<LI>
54<A HREF="expgui_cfg.html">
55Customization notes</A>
56</UL>
57Contributions of additional documents or improvements to me
58is greatly encouraged.
59</blockquote>
60
61<P><B>So what can EXPGUI do?</B>
62<blockquote>
63<dt>
64<i>Phase parameters</i>: EXPGUI can edit the cell and atomic parameters
65as well as the cell and atomic damping and refinement flags.</dt>
66
67<dt>
68<i>Histogram parameters</i>: Scale factor, background, diffractometer constants,
69phase fractions, profile terms can all be changed.</dt>
70
71<dt>
72<i>Least-Squares options:</i> control the number of cycles, the print options
73and F<sub>obs</sub> extraction parameters.</dt>
74
75<dt>
76<IMG SRC="note.gif">
77Creating new .EXP files and adding phases, histograms and atoms
78(EXPGUI version 1.17 and later).</dt>
79
80<dt>
81<IMG SRC="new.gif" HEIGHT=13 WIDTH=36>
82Editing and creating [hard] constraints on atomic parameters.
83</dt>
84
85</blockquote>
86
87<p><br><B>So what can't EXPGUI do?</B>
88<blockquote>Much more than it can do. At this time, EXPGUI can't
89delete atoms or change their type.
90It cannot create or edit soft constraints
91or other that atomic hard constraints. It cannot be used on
92magnetic scattering parameters or on single-crystal histograms. It can't
93even change the profile function number. It also can't change the
94excluded data regions.
95<p>I hope to add some of these capabilities in the future, but EXPEDT is
96a huge program and it is unlikely that anyone will replace it any time
97soon. I will consider adding more functionality if requested and the job
98is reasonably tractable.
99</blockquote>
100
101<p><br><B>What type of computers will EXPGUI run on?</B>
102<blockquote>EXPGUI requires Tcl/Tk. While that is somewhat restrictive,
103it still means that EXPGUI will run on many more platforms than GSAS does.
104Most of the development has been done in LINUX with some testing on SGI
105and Windows-95 systems. I expect that EXPGUI will run on all platforms
106where GSAS does (except perhaps VMS).</blockquote>
107
108<p><br><B>Who is to blame for EXPGUI?</B>
109<blockquote>The initial version of the GUI part of EXPGUI was created by
110Jonathan Wasserman (thanks Jon!) <a href="http://www.ncnr.nist.gov/staff/toby/">Brian
111Toby</a> is irresponsible for the rest.</blockquote>
112
113<p><br><B>EXPGUI would be much more of use to me if....</B>
114<blockquote>Gee, you want to add some features... Great! You have all the
115EXPGUI sources and Tcl/Tk is free. Oh, you want me to do it. Well, I might
116get to it if you ask, particularly if you help.
117I am looking for good ideas on how to design GUI's
118for different aspects of experiment editing,
119with an attractive, intuitive and compact GUI.</blockquote>
120
121<p><br><B>Mailing List</B>
122<blockquote>If you would like to get news about EXPGUI, please send
123<a href="mailto:brian.toby@nist.gov?subject=EXPGUI Mailing List">Brian.Toby@NIST.GOV</a> e-mail and I
124will send you information about updates and bug fixes.
125Having lots of users might also help me justify this project to my
126employers.
