Dear friends,
I have constructed a .top file for a CNT by g_x2top. to do this I
have added C-C interactions in .n2t file and also related ff in
.atomtypes.atp. I have also a .top file for a peptide by pdb2gmx.
My aim is to construct a simulation system in which I want to see the
adsorption.
I don't know the next steps, could you guide me for further steps?
You need to end up with a .top file that has the logical structure of
#include force field files
#include CNT.itp
#include peptide.itp
#include solvent.itp
[molecules]
CNT 1
Peptide 1
SOL 10000
and a coordinate file whose molecules are ordered exactly as in the
above field, and whose atoms within molecules are ordered exactly as in
the [atoms] fields in the .itp file. Your molecule names must match
those given in the .itp files.
See the examples in section 5.7.1-5.7.3 of the manual.
Mark
My second question; I have .gro and .tp files for both CNT and
peptide, do I need any other files such as .itp or .ndx?
Last question: Do you have such a tutorial?
best wishes
trevor
