Hi,
I now see what your problem is. This is specifically the psfgen plugin
that you're having trouble with, not simply loading PSF files with the CMAP
feature into VMD. The psfgen plugin doesn't yet read these CMAP files.
I'll have to defer to Jim as to when psfgen may be updated to support
CMAP in psfgen, as there's much more to this than merely reading the CMAP
records from the PSF files in the case of psfgen/NAMD.
