Hi Kendall,
Usually that would mean that there is no segment in your model that has a gap in chain A missing residues 331-336 (6-residue gap).  It could also mean that the sequence could not be aligned with your sequence file.  Is one of those possible?

Dear PHENIX developers,
I am trying fit_loops for the first time and getting error message:
“No suitable gap found matching residues”

I’m not sure what the problem is.

Best regards,
