I want to attach a molecules with the biomolecule, but unfortunately I do not have the reasonable force field for this molecule.
Now what I tried for to get force field is as follows:
1. I tried CGenFF and got a *.str file but the data in the file is different from my input file i.e. mol2 file.
2. I tried to get force field from swissparam website and received the different file as *.par, *.top file, I tried MD on this field it runs successful, but the question is that is this correct approach?
3. I tried parameter tool available in VMD too I got some output from it too, but I am not able to connect all the information.
Any guess what to do to get accurate force field parameter for my molecule.
your suggestions are highly appreciable.
