Hi,

I hope you do not mind I cc-ed modeller_usage here.

I am guessing you are using more than one template structure. If so, the problem probably arises because the input alignment aligns a distance in the target sequence with two or more distances in the template structures that are very different from each other. I suggest that you use the output of CHECK_ALIGNMENT to follow up on this suggestion and, if appropriate, edit the alignment of the structures with each other so that pairs of aligned residues in known structures do not span very different distances.

Best regards, Andrej
