|---|
| 11 | What is EXPGUI?<img SRC="2s.gif" align=RIGHT> |
|---|
| 12 | |
|---|
| 13 | <blockquote>EXPGUI is a graphical user interface (GUI) editor for GSAS |
|---|
| 14 | experiment (.EXP) files and shell which allows all the other GSAS programs |
|---|
| 15 | to be executed with a GUI, similar to the <a href="http://www.ncnr.nist.gov/~toby/tkgsas.html">tkGSAS</a> |
|---|
| 16 | shell. EXPGUI is not a replacement for the GSAS program EXPEDT, as there |
|---|
| 17 | are many things that EXPGUI cannot do. I have tried to put most of the |
|---|
| 18 | actions that I use most frequently and that could be easily accommodated |
|---|
| 19 | into EXPGUI.</blockquote> |
|---|

|---|
| 21 | <p><br>Is there documentation? |

| 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 |
|---|
| 42 | as well as the cell and atomic damping and refinement flags.</dt> |
|---|
| 43 | |
|---|
| 44 | <dt> |
|---|
| 45 | <i>Histogram parameters</i>: Scale factor, background, diffractometer constants, |
|---|
| 46 | phase 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 |
|---|
| 50 | and F<sub>obs</sub> extraction parameters.</dt> |
|---|
| 51 | |
|---|
| 52 | <dt> |
|---|
| 53 | <IMG SRC="new.gif" HEIGHT=13 WIDTH=36> |
|---|
| 54 | Creating 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 |
|---|
| 60 | delete atoms or change their type. |
|---|
| 61 | It cannot create or edit soft constraints |
|---|
| 62 | or hard constraints. It cannot be used on |
|---|
| 63 | phases with magnetic scattering or on single-crystal histograms. It can't |
|---|
| 64 | even change the profile function number. It also can't change the |
|---|
| 65 | excluded data regions. |
|---|
| 66 | <p>I hope to add some of these capabilities in the future, but EXPEDT is |
|---|
| 67 | a huge program and it is unlikely that anyone will replace it any time |
|---|
| 68 | soon. I will consider adding more functionality if requested and the job |
|---|
| 69 | is 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, |
|---|
| 74 | it still means that EXPGUI will run on many more platforms than GSAS does. |
|---|
| 75 | Most of the development has been done in LINUX with some testing on SGI |
|---|
| 76 | and Windows-95 systems. I expect that EXPGUI will run on all platforms |
|---|
| 77 | where 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 |
|---|
| 81 | Jonathan Wasserman (thanks Jon!) <a href="http://www.ncnr.nist.gov/~toby/">Brian |
|---|
| 82 | Toby</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 |
|---|
| 86 | EXPGUI sources and Tcl/Tk is free. Oh, you want me to do it. Well, I might |
|---|
| 87 | get to it if you ask. I am looking for good ideas on how to design GUI's |
|---|
| 88 | for different aspects of experiment editing, for example:how to code and |
|---|
| 89 | edit hard constraints with an attractive, intuitive and compact GUI.</blockquote> |
