But this doesn't help when it has to be bound to the protein. The bond (angle, dihedral, etc) has to be set and on top of that the myristic acid moiety has to be part of the same [ moleculetype ] definition, including consistent numbering. You can't do it with an #include. You have to have a .rtp entry and edit the file specbond.dat (http://oldwiki.gromacs.org/index.php/specbond.dat). Cheers, Tsjerk -- Tsjerk A.
