Dear Justin, Thank you for your reply. I have parameters from some manuscript and add all of them in force field. There is two parts of dihedral types in ffbonded.itp that one of them has func=4 and another has func=9. Also I have two types of parameters for dihedral;* Proper* and* Improper

Hi I want to add some bond parameters in ffbonded.itp file, and as I read in manual, unit of "kb" is "kj.mol-1.nm-2" and unit of "b0" is "nm". But I have these quantities with "kcal.mol-1.Å-2" and "Å". How do I convert these? Is it enough converting of kcal/mol to kj/mol for "kb" and "Å" to
