Dear Mark, Sorry about that mistake, the popc.itp file is began with these 3 lines:
;[ moleculetype ] ; Name nrexcl POPC 3 the error is: ERROR 1 [file "popc.itp", line 3]: Incorrect number of atomtypes for dihedral (1 instead of 2 or 4) Fatal error: Bonded/nonbonded atom type '1' not found! What is the relation between nrexcl and that fatal error?
