; If you get a complaint about missing dummy types from pdb2gmx ; is is straightforward to add it here. ; First, determine the bonded atom type (for most forcefields except ; opls it is probably identical to the nonbonded atomtype) for the ; next atom bound to your N or C atom. Check the constrainttypes ; section of the forcefield and determine which type of dummy mass ; is used for an N (or C) bonded to that atomtype. ; In the correct section below you can then add your atomtype ; (not bonded atomtype!), the type of the bound heavy atom, and the ; type of dummy mass to use in this case. ; ; If the dummy is a planar NH2 group you should just write planar ; after the N atomtype name. ; N.B: dummy masses must have names beginning with MNH2* , MNH3* , MCH3*.
