Hi VMD developers,
In the Molefacture plugin, I built one molecule, and I saved psf, pdb and
top. They looks fine except there is no improper list in the psf and top
files, I've used the force planar when I build the structure, so I am quite
confused about how to get the improper lists? Or maybe the improper list in
the psf file is not necessary as long as I have improper parameters in the
parameter files, NAMD will assign the paramters for these 4 atoms? Thanks!
