Hi, In addition to Mark's comments:

Position restraints are defined as part of molecule types. You can't include them outside the scope of a [ molecule_type ] block. You'll get the 'invalid order of directives' error for that. You have to include the position restraint include files in the respective molecule definition include files. Understanding how topologies and coordinates are put together is vital when doing anything already slightly out of the ordinary. Cheers, Tsjerk -- Tsjerk A.
