I am trying to model some systems where I am trying to use custom forcefields from the literature.  The funcitonal form seems to fit within the functions used by Forcite.  However I am having trouble getting the forcefields into a form that Forcite can understand.

At this point the forcefield editor does not work for these forcefields, since it does not expose enough functions, nor any type of equivalence table.  To get the terms into the forcefield I will have to manually edit a OFF file.  However there does not appear to be any easily available documentation on what format the OFF file uses.  Is there any documentation that anyone can point me to that explains the various options in the OFF file?

Thanks,

Brad.
