Hi Eddie,
What I believe you could do is use the *.top file that FFTK creates for
you. You could use psfgen wherein you read the FFTK-generated top file
(along with standard CHARMM top files) and generate a fresh psf. Only thing
is, you need to make sure your top file is updated (i.e. has the charges
etc).
Regards,
Chitrak.
