[AMBER] CartHess2FC

Dear Amber users,

I am trying to obtain some bonded parameters from QM frequency
calculations, using the CartHess2FC.py program in Amber. I am using
CartHess2FC.py version 3.0 for this purpose. However, when checking the
output I sometimes obtain weird values:

===========================Bond Parameters===========================
   Atom 1 | Atom 2 |Bond Force Constant|Equilibrium Bond Distance
LIG1.C | LIG1.S | (160.9+0j) | 1.8068

I was surprised to observe this behaviour and I do not understand the
reason for this to happen. Has anyone experienced such an error? I could
not find anything related to this issue. I would appreciate any feedback if
someone has already experienced this.

Many thanks!

Best regards,

Jon Uranga
