Hi Srijita,
You have to make sure that the molecules you have in your system are
defined in the topology file(s) that you are including. I think urea is
defined in either the top_all36_cgenff.rtf file. I am not sure about the
choline-o-sulfate, but you could look through the other topology files.
Hope this helps,
Chitrak.
