[gmx-users] RTP file formats
Hi everyone! The *.rtp file formats we have on Gromacs rtp file exmaples do not necessarily have the [dihedrals] or [impropers] part. They normally only have the [atoms] and [bonds]. In fact, the [bonds] section do not enumerate the constants or parameters. This is not what is written or shown as an example in the manual. Is is ok to just enumerate or list down the [atoms] and [bonds] but not including the rest? Thanks. -- gmx-users mailing listgmx-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!

Per the example in section 5.6.1, only the [bondedtypes] and [atoms] directives are mandatory, but in the case of a bonded molecule, I believe [bonds] are as well. The rest of the directives, if not otherwise specified, are constructed from the existing information. -Justin -- Justin A.
