Dear VMD users,
I am new to VMD and just learned how to use Automatic PSF builder to
create a psf file for a linear peptide.
Right now, I am dealing with a small cyclic peptide (connection through
the main chain).
With the pdb file of this peptide in hand, what should I do to generate
a psf file by using Automatic PSF builder?

Thanks a lot.
