Hi Maite,
The thing is, if pdb2gmx does not encounter a TER statement or chain
identifier, it usually tries to bind everything it finds together
consecutively. So, you could try to add a number of TER statements,
but still, it is better to generate the topology for your protein
separately by running it through pdb2gmx and then adding the things
together. That will also make your topology much smaller.

Hi Tsjerk:
But, i think the problems is that pdb2gmx program see the membrane
how a protein and it tries to tie the peptide with the membrane. The
topology of dppc membrane appear in the ffG53a5.rtp file of gromacs.
What can i do? Should i create a peptide.top file and include it a
lipid.itp and dppc.itp file?
The lipid.itp file i took from Dr. Peter tieleman site is for GROMOS87
forcefield and i use GROMOS96 forcefield.
Thanks for the help,
Maite
