11What is EXPGUI?<img SRC="2s.gif" align=RIGHT>
12
13<blockquote>EXPGUI is a graphical user interface (GUI) editor for GSAS
14experiment (.EXP) files and shell which allows all the other GSAS programs
15to be executed with a GUI, similar to the <a href="http://www.ncnr.nist.gov/~toby/tkgsas.html">tkGSAS</a>
16shell. EXPGUI is not a replacement for the GSAS program EXPEDT, as there
17are many things that EXPGUI cannot do. I have tried to put most of the
18actions that I use most frequently and that could be easily accommodated
19into EXPGUI.</blockquote>
20
21<p><br>Is there documentation?
22<blockquote>Some. There is:
23<UL>
24<LI>
25<A HREF="http://www.ncnr.nist.gov/~toby/expgui/expgui.html">
26A User's Guide</A>, complete with lots of pictures

28<A HREF="http://www.ncnr.nist.gov/~toby/expgui/expgui_Win_readme.html">
29Installation notes for Windows</A>

37
38<P>So what can EXPGUI do?
39<blockquote>
40<dt>
41<i>Phase parameters</i>: EXPGUI can edit the cell and atomic parameters
42as well as the cell and atomic damping and refinement flags.</dt>
43
44<dt>
45<i>Histogram parameters</i>: Scale factor, background, diffractometer constants,
46phase fractions, profile terms can all be changed.</dt>
47
48<dt>
49<i>Least-Squares options:</i> control the number of cycles, the print options
50and F<sub>obs</sub> extraction parameters.</dt>
51
52<dt>
53<IMG SRC="new.gif" HEIGHT=13 WIDTH=36>
54Creating new .EXP files and adding phases, histograms and atoms.</dt>
55
56</blockquote>
57
58<p><br>So what can't EXPGUI do?
59<blockquote>Much more than it can do. At this time, EXPGUI can't
60delete atoms or change their type.
61It cannot create or edit soft constraints
62or hard constraints. It cannot be used on
63phases with magnetic scattering or on single-crystal histograms. It can't
64even change the profile function number. It also can't change the
65excluded data regions.
66<p>I hope to add some of these capabilities in the future, but EXPEDT is
67a huge program and it is unlikely that anyone will replace it any time
68soon. I will consider adding more functionality if requested and the job
69is reasonably tractable.
70</blockquote>
71
72<p><br>What type of computers will EXPGUI run on?
73<blockquote>EXPGUI requires Tcl/Tk. While that is somewhat restrictive,
74it still means that EXPGUI will run on many more platforms than GSAS does.
75Most of the development has been done in LINUX with some testing on SGI
76and Windows-95 systems. I expect that EXPGUI will run on all platforms
77where GSAS does (except perhaps VMS).</blockquote>
78
79<p><br>Who is to blame for EXPGUI?
80<blockquote>The initial version of the GUI part of EXPGUI was created by
81Jonathan Wasserman (thanks Jon!) <a href="http://www.ncnr.nist.gov/~toby/">Brian
82Toby</a> is irresponsible for the rest.</blockquote>
83
84<p><br>EXPGUI would be much more of use to me if....
85<blockquote>Gee, you want to add some features... Great! You have all the
86EXPGUI sources and Tcl/Tk is free. Oh, you want me to do it. Well, I might
87get to it if you ask. I am looking for good ideas on how to design GUI's
88for different aspects of experiment editing, for example:how to code and
89edit hard constraints with an attractive, intuitive and compact GUI.</blockquote>
