Hi--

  I've figured out the cause of your problem writing a pdb which
contains unknown atoms.

This is a bug in xplor-nih in versions up to and including 2.0.3. It
will be fixed in version 2.0.4, which I will try to release in the
next week.

Until then, here's a workaround:

  In the xplor script, before the write coor statement, place the
following three lines:
command("vector do (x=9999) (not known)")
command("vector do (y=9999) (not known)")
command("vector do (z=9999) (not known)")
