I'm not sure what you're trying to do here but the alignment file
sequence has to match that in the PDB file. You clearly have 3525
residues in the alignment file but you are asking Modeller to read
residue 15:A through 1234:A (which does match the A chain range for 6nzk
at PDB). Obviously 15-1234 isn't 3525 residues (not sure how you got
4026 unless you edited the PDB file - 6nzk from PDB has 1175 residues).
