Dear Justin: Thank you for reply. g_x2top worked correct as you suggested when I added "-nopbc" option.
I have other questions about graphite simulation. The top/rtp file(opls-aa) generated by g_x2top missed improper dihedral term , to keep a carbon in plane, whether it is better to add the missing terms in topology file or need other corrections ? Thank you in advance! sincerely zhhxu PhD student Department of Biochemical Engineering Institute of Process Engineering Chinese Academy of Sciences -- gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/Search before posting! * Please don't post (un)subscribe requests to the list.
