Charmm36 parameter preparation for a small molecule

Dear Gmx users,
I want to simulate folding simulation of peptide in water-HFIP solution using gromacs.
I would like to prepare charmm36 parameters for hexafluropropanol (HFIP) instead of using CgenFF for the parameters.
Can I convert the parameter from Gromos96 force field to Charmm36?

Best regards,


You can’t convert one force field to another.

no, Gromos96 force field is united atom and charmm36 is all atom.
