I was getting an error while running the snugdock that I solved using the clean_pdb.py command. When I ran flags file using snugdock @flags file, another error came up saying "the antibody doesn't contain start or end of residue of cdr loop H1. Please check pdb is renumbered properly and passed -numbering scheme option matched the PDB.This could also mean missing density in the cdr loop. Loop modeling application can be used to fill missing residues."
Not sure what is going wrong. I checked the numbering but it looks correct. Please advise on this. Thanks!
