I'd only add that GSAS-II makes simulated patterns the same way as
GSAS in that you need to choose a scale factor (see Sample
Parameters) and suitable background (see Background). A bit of
trial & error might be needed to get something sensible. NB: do
set the number of cycles=0; otherwise GSAS-II will refine to your
simulation!<br>

<div> You are correct that this needs a tutorial — someday! The
process of simulating a pattern is similar to setting up a
refinement. However, for a dataset, on the import/powder data
menu you will see a simulate option. </div>

<div> You probably will want to keep the histogram instrument
and sample parameters unchanged from their defaults, but will
want to change the ones on the Phase/Data tab. </div>

<div> There is no powpref in GSAS-II. Use the Calculate/Refine
option to compute the simulated pattern. </div>

</div>
<div>I am new to both GSAS and GSAS-II. I am trying to
simulate an x-ray dataset for textured Magnesium. I know
how to create a simulated dataset in GSAS using POWPREF
and GENLES. However, I do not know how to simulate a
dataset in GSAS-II or where the corresponding options are
for POWPREF or GENLES. How do you simulate a diffraction
pattern using GSAS-II? Is there any good documentation
that I missing? Any help would be appreciated.</div>
