You may add glycan groups to your structured domains with the ATSAS command-line program GLYCOSYLATION.
We could not reproduce this. You should get an error message like "Domain 2: fixation is not compatible with initial configuration"; CORAL will exit with a non-zero exit code. Please make sure you use the latest ATSAS package.
Could you please point us to some documentation on how the fourth column should be interpreted? So far we've seen SANS data in four-column format only from KWS1 (FRM2, Munich).
