Dear FFTK experts,

I have a question regarding the Scan Torsions section of FFTK. I would
like to parameterize 14 diherdrals, that are all listed in my par file.
When I use the "Read from PAR" button on the "Dihedrals to Scan" panel and
load the par file, FFTK only lists 4 torsion angles. I do not understand
why this is.

When I use the file with the "Read from PAR" button on the "Dihedral
Parameter Settings" of the "Opt. Torsions" section, all 14 dihedrals are
listed correctly.

I added manually the missing ten dihedrals for optimization, but I was
wondering whether I am missing somthing here. I am supposed to generate
gaussian input files for each of the diherals be parameterized, right?
I am attaching my pdb, psf and par files.
