26 | The following pages show how to use EXPGUI to |
---|
27 | perform the same tutorial refinement for Nickel powder, |
---|
28 | presented in the |

29 | <A HREF="http://www.nist.gov/cgi-bin/exit_nist.cgi?url=http://www.ccp14.ac.uk/ccp/ccp14/ftp-mirror/gsas/public/gsas/manual/GSASManual.pdf"> |
---|
30 | GSAS manual</A> (pages 18-63 in the 9/1/94 edition) but |
---|
31 | using EXPGUI instead of EXPEDT, as done in the manual. |
---|
32 | |
---|
33 | <P> |
---|
34 | <I>Note:</I> |
---|
35 | <blockquote> |
---|
36 | while it is possible to have your working GSAS files |
---|
37 | (for example the .EXP file) in a separate directory from |
---|
38 | the raw data file(s), I discourage this practice as it then |
---|
39 | becomes quite difficult to later copy or move the .EXP |
---|
40 | file from one directory or computer to another. |
---|
41 | For this reason, I suggest copying the data (.RAW) files |
---|
42 | into the directory where you will create the Experiment |
---|
43 | (.EXP) file. |
---|
44 | <P> |
---|
45 | For this example, I am working in directory |
---|
46 | <tt>/home/toby/work</tt>, and the |
---|
47 | data files and parameters files are in directory |
---|
48 | <tt>/home/toby/gsas/example</tt>, so |
---|
49 | I copy the Nickel data and instrument parameter file using UNIX commands: |
---|
50 | <PRE> |
---|
51 | cp /home/toby/gsas/example/nickel.raw /home/toby/work/ |
---|
52 | cp /home/toby/gsas/example/inst_tof.prm /home/toby/work/ |
---|
53 | </PRE> |
---|
54 | For Windows I would likely copy the files by dragging their icons between |
---|
55 | the appropriate folders. |
