Thanks Mr. Goette, But error list is not so long , its simple as
Fatel error: atom type 'CR61' not found in the topology , where 'CR61'
is the atom type occurs
first in my drug itp file made from PRODRG.
Otherwise could you suggest me any other forcefield otherthan OPLSA to
treat Fe(II) in active site and also
fix the drug atoms types compatiablity.
With thanks,
B.Nataraj
