That script also writes out a psf file, and this file actually contains
bonding information (the pdb contains only coordinates). Rasmol and
Pymol have to guess at bonding if given only a pdb, and probably get
confused by the strange configuration of the extended strand. I suspect
that nothing is wrong with protG_mkpsf.inp, but the python psf
generation scripts (mostly in eginput/PSF_generation) are more
featureful.
