</div>
<div> I will need to check if a roughness parameter has been put into the code yet. I think not. </div>
<div><br>
</div>
<div> GSAS-II is much more stable than GSAS and does not have damping because it is not needed. </div>
<div><br>
</div>
<div> There are a number of tutorials that can be found in the help menu or here:
<a href="https://subversion.xray.aps.anl.gov/trac/pyGSAS">https://subversion.xray.aps.anl.gov/trac/pyGSAS</a></div>
<div><br>
</div>
<div> GSAS-II can read GSAS instrument parameter files. It does offer a more straightforward format, but I don't think that has been documented yet. You can write parameters out with that format though. Note that when asked to supply a instrument parameter
file, one can press "Cancel" and then select from a default. </div>
<div><br>
</div>
<div> One can export results in various formats from the menu with that name and how to write code to support other formats is documented. </div>
<div><br>
</div>
<div> There is a need for much more documentation, but at present Bob and I are putting much more effort into writing more code. Someday we will catch up, but volunteers are much welcome. </div>

differences between GSAS and GSAS II results. Mainly, because some parameters that I refined in GSAS I could not find in GSAS II. For instance, I did not see how to refine roughness. Another question comes from the possibility of acting with damping factors.
