Amanda,

A “/” in the alignment means a chain break for MODELLER. So two chain breaks (in both the template and target sequences) and the requisite number of gaps in the template sequence should work.

Subject: [modeller_usage] Gaps in pdb file

Dear Modellers,

I'm relatively new to Modeller, and I have a question which I hope has an easy answer. Whenever the pdb file for a solved structure has a gap in the residue numbers (so, for instance, it jumps from residue 300 to 315), I get an error saying that the number of residues in the alignment file and the pdb file are different. How can I fix this problem?

Thanks!
