Hi,
  I don't recall if anyone replied to this, and I was out sick for a
few days after your email, but it is easy to write a .js file from
a given PSF/PDB pair by making an "all" atom selection and doing:
  $sel writejs filename.js

If your structure gets too large for psfgen to handle, you'll either
need to use the standalone version of psfgen that can write js files
directly, or I can make a special build of VMD for you that includes
a psfgen plugin that knows how to work with the js files. Eventually
this will be the standard version of psfgen shipped with VMD, but
I can't switch over to it until we get a few issues resolved for the
Windows version of VMD/psfgen.

Cheers,
  John Stone
