Hello Sir/Ma'am,
I want to generate ligand topology files (lig.top and lig.crd) for my
ligand. For this, first I generated .prep and .frcmod files using
antechamber and parmchk respectively without any error. Further, I am
trying to generate topology for the same molecule with tleap, but I am
getting the following errors. I am attaching the error herewith, please
help to solve the problem:
