The user contributed program, topolbuild, will
generate
*.gro, *.top, and *.itp files from a .mol2 file that
uses Tripos atom types. If the TAFF* files (TAFF_VDW,
TAFF_TORS, TAFF_OOP_BEND, TAFF_BOND_STRETCH, and
TAFF_ANGLE_BEND found in sybylbase/tables/ascii) are
available, the topology thus generated can be written
with Tripos FF values assigned to all quantities.
This may get you started.
