Hi,
One issue to consider is that many programs, when esd's of each datum
are not given explicitly, estimate these as sqrt(I). Further, many
programs weigh the data using these esd's. Therefore, since it is
desired that esd/I remain a constant, if you do multiply your data by a
constant, the eas

Hello
I am a new user of GSAS, but I have a problem.
I can't to convert my files to the GSAS format. I trying with powder and
convx software, but I don't have good results. I trying with the option
"convert" in GSAS, but nothing, too.
I send you one file (attache to this
your data are free format with intensities as a real variable. Using
excel or any equivalent you can convert in integer intensities (e.g.
multiplying by ten to avoid errors with low values) which is the usual
data input ("counts").
Step 2 is then to convert the free 2th-I (real-integer) file into G

I am using powder to convert files and using well in GSAS. Use Powder and click
open file - chose the option with your extention. Then save the file as *.gsa.
It should work.

Good afternoon,
Now I haven't ConvX here, but once I had done so:
you can copy angle and Intensity columns from UXD file on a NotePad
(Block Notes), saving it as a file *.txt.
Then with ConvX you convert this simple ASCII file (select file ASCII,
2theta/Intensity) in a file for GSAS (type file: G
