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?
Thank you
