Hello,
I recently started using GSAS for powder diffraction refinement. I have a
Bruker D8 Advance system. I was being able to open my files without any issue,
and I had started the refinement procedure successfully, but a couple of
updates later I am getting the error message posted at the bottom of this
message.
Did any of the updates modified the RAW reader? Is this a GSAS bug? Should I
uninstall the program and reinstall it?
Thank you for your program, and your help!
Sandra
