Dear Sergey:
You may check out this thread:
http://amber.ch.ic.ac.uk/archive/200508/0081.html
The error message means that the bond, bond angle, and torsion paramters for
C2 type have not been defined/developed in AMBER (although the type has been
defined). If you need the parameters, you may need to develop your own.
It may be a good idea that you try antechamber to see the atom-type
assignment which might be more compatible with AMBER ff parameter sets.
