============================================================================
General advice about asking for help:
What we need to know in order to help: *exactly* what you did (i.e. the
commands you used). You are telling us what you intended to do (e.g. "change
the naming to GAFF") rather than what you actually did.
Second: reporting a result like "all without success" is also of no help.
Please report the exact symptom or error message.
============================================================================
Specific advice about your problem:
Having said that, the loadMol2 command in tleap is primarily designed for
small molecules. If you have a protein, convert the mol2 to pdb (presumably
using whatever software created the mol2 file...) and load the pdb file into
tleap. For a protein, you almost certainly do not want to use the GAFF force
field; use leaprc.ff14SB, unless you are experienced enough to know for sure
that you want some other option.

...good luck....dac
