Dear modeller... ..here is mine TOP file, I've tried to align it with both pdb from Brookheaven and genereted by Sybyl (free of hetero atoms and Ca) but it fails...

ERROR: dispers_247E> internal error : 1263 1267 recover____E> ERROR_STATUS >= STOP_ON_ERROR

PDB file have 5 subunits and I try to align it...failed Could I use another alignment programm? and hand-make my own alignment file? (I've tried one but it fails...) Could you look at the alignment and top file???
