Hey Mark sorry for the inconvenience I have caused you. CYSh file was just
for an example.
And now I have generated the itp file using topolgen.
I would like to run MDS on this particular molecule alone with any protien.
What should I do for that.
Start with a tutorial to get yourself familiar with protein-ligand systems.

Also note that a TopolGen topology is based on a lot of assumptions. You should
do some basic validation, at least. See the OPLS-AA papers for the types of QM
calculations you should do.

Thank you.

Hi,
There's not enough information here for anyone to help you (and you can't
attach files to send to the list). Why didn't you find the generated
topologies useful? Why do you care about CYSH?

I have tried Ligpargen to generate topology for a molecule and I dont
find
it useful. And totally unaware how to use topolgen or topolbuild.
Now I am trying to craft my topology manually. I would like to get some
guidances.

here how to determine these forcefields?
