I am trying to optimize dihedral force field parameters for a structure
using FFTK.
When I run the gaussian to scan for the dihedral angles with the
modredundant option I get an error (due to the modredundant geometry) so I
scan using cartesian geometry which is performed correctly. However, when I
try to run the optimization in FFTK using these gaussian log files I get
the error "can't read scanDihDef: no such variable".
Is there any way to make VMD read correctly the gaussian log files
resulting from dihedral scan with cartesian geometry otpion?

Many thanks for your time
