Hi, it works

before I thought it might share some similarity with 4.0.7 which some bash file helps to update the ff information.

The mechanism changed in 4.5. Now "forcefield.*" files do something significant. Look at the contents and see.

Mark

Thanks,

        Hi,

        Anyone has successfully tried to add some new force field in
        the default
        force field (in 4.5)

        so pdb2gmx can show up the (newly-added) force field which
        will also be
        recognized by gromacs,

        Thanks,

        lina

    Yes it's easy technically.
    Just copy e.g. oplsaa.ff to new.ff and edit the files in that
    directory (not easy).
