Dear all,
 
is the SCEE for electrostatics and SCNB for VDW 1-4 interactions written in the prmtop file ... for GAFF
 
also in the amb2grmx.pl these VALUES are defaulted to the one used for GAFF ....0.5 VDW, 0.83 EEL
This script converts Amber topology file to gromacs ..is this possible !
 
MANY THANKS
Fati

This generally means that atom or residue names in the pdb file don't match
those in the DXQ-11.mol2 file you created above. You have to make them
exactly match, and the names are case-sensitive.

Also, study the leap.log file carefully: there should be other messages
pointing out the problem, especially if my diagnosis is correct.
