Have you ever seen a script/tool that allows for transformation of the Gromacs force field files
into CHARMM force field files? I can see that there is a Pythons script that does the other
Also I could use a tool that creates *.psf file from *.top file. I googled for that and found thishttp://www.ks.uiuc.edu/Research/vmd/script_library/scripts/top2psf/top2psf.pl
Would you recommend anything else?
