Dear All,
I ran the x2top command and successfully generated a topology. However,
the topology file has duplicate bond, angle, and dihedral parameters and
missing Van der Waals parameters. I am including sections of my topology
file for your perusal. Please let me know why this is occurring and how
to solve this problem?
Much thanks.
Darrell
