[AMBER] Protocol to optimize bonded parameters for GAFF2

Dear all,

I would like to optimize some bonded terms with high penalties for a ligand that contains only C,H,N ans O atoms using GAFF2.

- Is there any articles or tutorials that explain in details the approach (QM basis sets and codes to use for this task)?

- An other question : For GAFF2, what is the threshold value to determine that a parameter should be re optimized? Is it the same value for CHARMM/CGENFF i.e. PENALTY > 10?

Thank you for your help and insights

Stéphane
