Hi Justin,
Thanks for the expedient reply. I referred MARTINI but after
converting 1A8G.pdb to 1A8G_CG.pdb i.e. CG structure of protein I dnt
know how to make the topol.top and conf.gro files for that and also I
am not able to generate the posre.itp file with this CG structure
because it says the fatal error : Incomplete ring of HIS 69. So I
don't know how to proceed now and do my simulations.
http://md.chem.rug.nl/~marrink/MARTINI/Parameters.html
See the "Peptides and Proteins" section. There are several scripts - a Perl
script that writes your topology based on sequence and secondary structure
information, and an awk script that converts the structure from atomistic to CG.
Note that the awk script is incorrect; each printf line needs to contain $5
between $4 and $6.

Thanks,
Sunny
