Hi,<br> Actually, I believe that only one force field (ffgmx) currently has an n2t file, at least as recently as 3.3.1. I would try running a find or locate command to see if you even have the n2t files to begin with. I also believe I read earlier on the mailing list that the CVS branch has some improvements to the x2top program which may be helpful. If not you may need to make one for your molecule.
