Hi all, I would like to add that you can also find the atom type definitions (perhaps in a more human-readable format) in the original MMFF paper:
Halgren, T. Merck Molecular Force Field. I. Basis, Form, Scope, Parameterization and Performance of MMFF94. Journal of Computational Chemistry. Vol. 17, 490-519 (1995).

Definition are stored in Code/ForceField/MMFF/Params.cpp (defaultMMFFDef). You may find them here in a more human-readable form: https://github.com/openbabel/openbabel/blob/master/data/mmffdef.par Cheers, p.

I want to get the definition of the atom type which the number represents. I wonder if there's a dictionary or a documentation that contains the atom type meaning or SMARTS of each number ?
