Subject: AMBER: leap.log warnings

Dear Amber Users:

When I build topology and coordinate files using leap, it looks fine--
just give out a list of 'old PREP-specified impropers'. But I find the
leap.log shows many warnings like:
 ** Warning: No sp2 improper torsion term for CY-HC-CX-HC
        atoms are: CAB HVC2 CBB HVT2

What does it mean? Could it has influence on MD? Any help would be
highly appreciated!

Best Regards!
