GSAS Nickel example using EXPGUI (part 8)
8. Run GENLES
At this point, we are ready to run GENLES to perform a least-squares
refinement. GENLES can be run from the appropriate
button on the button bar, by typing Alt-G, or using the GENLES command
in the Powder or Xtal menus.
As soon as GENLES is started, a box appears on the screen
showing the refinement status. (See below).
As the refinement progresses, the LIVEPLOT window automatically
updates, where the contents have
previously been described.
When GENLES is finished and the window is closed, press "Load new"
to cause the revised .EXP file to be read. (Pressing
"Continue editing" would reject the results of the refinement.)
To examine the results of the refinement in more detail, consult the
.LST file. This can be examined using the LSTVIEW program. This program
is shown above. Like LIVEPLOT, LSTVIEW is updated as the refinement
progresses.
The GSAS tutorial in the manual demonstrates use of POWPLOT to
look at other aspects of the data, such as error analysis. This can
be done by pressing the POWPLOT button or accessing POWPLOT from the
menu bar.
