Hi all,

first I would like to thank you for your help, I just finish to
parametrize my first molecule.

but I have still 2 questions:

- there is a new option in the "built par" menu, wich is called "Prepare
Parameterization from CGENFF Program Output" and before starting
using FFTK, I tried the all CGENFF procedure. So I have the output of
CGENFF and I create a par file from it. So the question is: how can I
use it
in the FFTK process? can I add it when parameters files (both in
progress or pre-defined) are asked?

- I know that FFTK does not include a tool for Improper, but can I
assignate Improper by analogy (example: between existing piridine and

thank you
