248. Run GENLES
25</H1>
26At this point, we are ready to run GENLES to perform a least-squares
27refinement. GENLES can be run from the appropriate
28button on the button bar, by typing Alt-G, or using the GENLES command
29in the Powder or Xtal menus.

33As soon as GENLES is started, a box appears on the screen
34showing the refinement status. (See below).

39As the refinement progresses, the LIVEPLOT window automatically
40updates, where the contents have
41<A HREF="nickel6.html#liveplot">previously been described.</A>

45When GENLES is finished and the window is closed, press "Load new"
46to cause the revised .EXP file to be read. (Pressing
47"Continue editing" would reject the results of the refinement.)

50To examine the results of the refinement in more detail, consult the
51.LST file. This can be examined using the LSTVIEW program. This program
52is shown above. Like LIVEPLOT, LSTVIEW is updated as the refinement
53progresses.

55The GSAS tutorial in the manual demonstrates use of POWPLOT to
56look at other aspects of the data, such as error analysis. This can
57be done by pressing the POWPLOT button or accessing POWPLOT from the
58menu bar.
