If you are following the tutorial, you are using ffgmx, are you not? These atom types are indeed part of this force field. Have a look at ffgmx.atp and you will find all of them. I suspect an error within the topology, perhaps a typo in the include statement. -Justin > > What should I do to eliminate the error? > > Can you please give me the other corresponding atom types that may be > used for these unrecognised atom types? > > > > the drg.itp file that I used with the atom types CB, CR61 and OS > -------------------------------------------------------------------------- > ; > ; > ; This file was generated by PRODRG version 061128.0522 > ; PRODRG written/copyrighted by Daan van Aalten > ; and Alexander Schuettelkopf > ; > ; Questions/comments to [EMAIL PROTECTED] > ; > ; When using this software in a publication, cite: > ; A.
