Hi ...,
You should have had a look at the topology file format in an earlier step.
At the end is a listing of molecules. As it says in the tutorial, you
replaced solvent by ions, and you have to make changes in the topology file
to match that replacement. Open the file in an editor, have a look ar

Hi Sonika,
cmake needs a specification of the path where the source code is. In
addition to that, it is best to build it in a separate directory. As
explained on the website, in your gromacs directory:
mkdir build
cd build
cmake ../
make
make install
Hope it helps,
Tsjerk
On Tue, Jul 2, 2013
You need to call the newly compiled code. Either install the new version
and source GMXRC appropriately, or use a full path to the new version in
the build tree.

Indeed, this
kind of problem is most easily solved by making a new
"residue" that
contains the whole chromophore, such that it links to its

with normal peptide links.

Yes, Mark is exactly correct about the glitch. I had just forgotten to
change this default charge in the ffnonbonded.itp when copying from
another atom. As mentioned this has no impact as these charges are never
used by pdb2gmx.

used, then an exact copy/paste of the error message.

Hi!!
I am new to short peptide simulations at low temperatures.
I want to run a MD of short peptides of 6 - 12 residues at 276 K.
For this the scheme I wish to follow is :
1. Run a short energy minimization of the peptide + water system to
remove short contacts
