Dear Landry,
If you didn't find instructions on the mailing list then I suspect
that you didn't try too many keyword combinations. It's also a good
idea to peruse the most recent couple of weeks from the archive to
ensure that the same question was not just answered a couple of days
ago (it was, by me).
And please keep this on the mailing list. If you wish, you can also
send me an email to notify me of your recent post to the mailing list.
Chris.

Subject: membrane simulations with gromacs
To: [EMAIL PROTECTED]
Dear Chris Neale
I'm a Ph.D student in computational chemistry and I try to simulate a
GPCR in a
membrane bilayer of POPC.
Normally, I work with Amber package but Gromacs is more suitable for GPCR
incorporation in a membrane bilayer.
Like POPC parameters aren't in the database of Gromacs, I try to use
Gromacs on
simple case : the popc128b.pdb of Pr. Tieleman (I have also downloaded the
popc.itp and lipid.itp).
When I do pdb2gmx -f popc128b.pdb -o popc128b.gro -p popc128b.top, I have the
error : POPC isn't in the database (ffG53a6.rtp).
I understand this error but I don't know what I must do. Indeed,
pdb2gmx hasn't
commands for incorporate the popc.itp.
I read the manual and the gmx-users mailist and I don't find. So If
you can help
me please.
Sorry for this very basic question.
King Regards.
