Thank you for your reply,
I am asking you again same question, EXTREMELY SORRY for my stupidity,

Dear Suryanarayana,
This error itself tells you that the particular residue 'DAL' is not
available in the residue topology database of the force field you are using
for your simulation. You can check that by yourself in the *.rtp file of
corresponding force field.
The way out of this situation is

Thank you Justin for these correct explanation
Its really clear my lot of queries..
For the tutorial, NPT is conducted with restraints on all protein heavy
atoms. The production runs are conducted by restraining only one chain for
practical reasons.
These is my question ;

Dear Gmx Users,
I want use distance restraints of 3 atoms belonging to 3 different
moleculetypes. In this case shall I create and index file of those atoms
and then use:
genrestr -f X.pdb -n index.ndx -disre -o disre.itp ?
Under which topology file shall I add:
#ifdef DISRES

Hello. Is it possible to perform MD for protein-ligand interactions in
implicit water? And what about the precision of this kind of MD's? Are
they differ strong from these with explicit water?

Hi Gromacs users,
I have a problem getting a snapshots using trjconv. If you could help me, I
would be very grateful. Below, I try to explain what I did and problem
happened.
Firstly, I have done 10ns long simulation (several peptides in a box). And
then, using the outputs of that simulation

Hi Rama,
Thanks for your quick reply.
Catenate two trajectory with help of trjcat -h
to get snapshot of particular time use trjconv -dump time
use appropriate pbc option
I have also used trjconv with -dump and -pbc nojump options, but still I
have same problem.
you are using -b 1 -e 1
Hi ,
You run extended simulation of 10 ns on your first 10ns simulation .
You get traj20ns.xtc.
these new trajectory contain all the tme frame from onwards 10ns.
So if you are giving command

snapshot20ns.gro (Note: traj20ns.xtc is

Dear gmx users,
ACE is defined in CHARMM-27 .rtp file, but I don't see this residue in
CHARMM-36 .rtp file . Is it OK, if I add the ACE from CHARMM-27 into CHARMM-36?
And use the CHARMM-27 [ACE] parameters in CHARMM-36?
Thanks in advance.
Sincerely,

Hi Steven,
So it did what you told it to do. You want -chainsep no or none. Doing
it from the top of my head, so I'm not sure. But it'll be listed in
the help what options there are.

Okay,okay, I give in. To settle this again, I looked it up, and among

That allows you to merge chains. I guess there'd be sense in just

Sure, CHARMM 36 is just a modification to the lipids. The protein (and other

Dear Users:
Summary:
I believe that there is some problem in the residue numbering routine that is
used by editconf and trjconv
that exists at least in 4.5.3 and 4.5.5, but not in 4.0.7, and that this is
somehow related to the ACE residue.
Details:
I have a system with two peptides, water, and
