IS the parameters for a residue in CHARMM36 and CHARMM27 the same?


I would suggest you do a bit of reading about the CHARMM force field hierarchy and why they are named as they are. If you're parameterizing a new residue you can do it for either, or both, depending on the parameter set. In your case, I'd suspect your formyl parameters are going to be universal between CHARMM27 and CHARMM36, but don't let my suggestion be your justification. If a reviewer asks, "some guy on the Internet said it" is not sufficient justification ;)

Thanks in advance,

Maybe, try it and see. Swiss-Param might also be an option.
