Thanks for your answer. How can I tell which ones I should restrain? all no-H atoms? in most general situations.

When running genrestr without an index file, you can choose from any of the default groups. If you provide an index file, any group can be chosen. The default behavior of pdb2gmx is to generate a posre.itp file that restrains all heavy (non-H) atoms. You can do the same with genrestr if you want, but again, the atoms you want to restrain depend on your goals. -Justin > > Thanks with regards, > > lina > -- ======================================== Justin A.
