[AMBER] problem with membrane embedding

Hi AMBER users,

I tried to embed a protein in a POPC lipid bilayer using VMD. The generated pdb is unrecognised by amber. It has weird atom names that are not present in the lipid forcefield file or its extension.

A sample is here:

ATOM 1 N POPCL 1 -33.304 -39.250 20.920 1.00 0.00 L11 N
ATOM 2 C12 POPCL 1 -32.577 -38.468 22.038 1.00 0.00 L11 C
ATOM 3 H12A POPCL 1 -31.812 -37.824 21.442 1.00 0.00 L11 H
ATOM 4 H12B POPCL 1 -32.055 -39.156 22.715 1.00 0.00 L11 H
ATOM 5 C13 POPCL 1 -33.428 -38.491 19.695 1.00 0.00 L11 C
ATOM 6 H13A POPCL 1 -32.514 -37.985 19.477 1.00 0.00 L11 H

same for the water and ions.

Is there a trick to convert the file to an AMBER-friendly format?

Regards,

Mohammad
