26<H1>Introduction</H1>

28The following pages show how to use EXPGUI to
29perform the same tutorial refinement for Nickel powder,
30presented in the
31<A HREF="http://www.nist.gov/cgi-bin/exit_nist.cgi?url=ftp://ftp.lanl.gov/public/gsas/manual/manual.pdf">
32GSAS manual</A> (pages 18-63 in the 9/1/94 edition) but
33using EXPGUI instead of EXPEDT, as done in the manual.

35<P>
36<I>Note:</I> 
37<blockquote>
38while it is possible to have your working GSAS files
39(for example the .EXP file) in a separate directory from
40the raw data file(s), I discourage this practice as it then
41becomes quite difficult to later copy or move the .EXP
42file from one directory or computer to another.
43For this reason, I suggest copying the data (.RAW) files
44into the directory where you will create the Experiment
45(.EXP) file.
46<P>
47For this example, I am working in directory
48<tt>/home/toby/work</tt>, and the
49data files and paramters files are in directory
50<tt>/home/toby/gsas/example</tt>, so
51I copy the Nickel data using UNIX command:
52<PRE>
53       cp /home/toby/gsas/example/nickel.raw   /home/toby/work/
54       cp /home/toby/gsas/example/inst_tof.prm /home/toby/work/
55</PRE>
56For Windows I would likely copy the files by dragging their icons between
57the appropriate folders.

87Sample .EXP files have been saved at points through the tutorial. These
88are indicated in the tutorial as ".EXP shapshots". These files have been
89reformatted for DOS/Windows, but EXPGUI users will have no trouble
90using them on either platform.
