Hello All,
Im trying to create the parameter files of a configuration. The molecules involved are Propylene Carbonate, Ethylene Carbonate, PF6-, Graphitic Sheets and Lithium. I previously had problems with the graphite and thanks to you guys I was able to fix it. Now, there seems to be another problem with the Graphic Sheets. I will go through the method to show what I did.
Since the Graphite is the only element I'm having problems with, I will show the .frcmod file for it.
I created the file as follows:
parmchk -i gra_test.mol2 -f mol2 -o frcmod
the resulting file and its contents:
gra_test.frcmod
remark goes here

Apparently I have "**No torsion terms for" multiple bonds. I looked and apparently I can manually input these torsion angles but I don't know where to find them after much time of looking. Could someone help me in fixing this issue.
Thanks
