You need to provide much more information about your ligand. Just saying
"directly from antechamber" is a little vague. Most often, having an atom
without a type means that you loaded a pdb file (or mol2 file, or something
with coordinates) whose names don't match those in the library you created
for the "SUB" residue. But without knowing either (a) what antechamber
commands you used; and (b) what LEaP commands you used, it's pretty much
impossible to help much.
