Good luck !

Those with a sense of humour.  (And, please, don't call
me "boy"; I'm at the other end of the Atlantic, so
"old chap", "lad" or "old bean" would be acceptable).

Then, for Heaven's sake, do *NOT* use O.  Wait until one of the
me-too O-rip-offs offers you a precooked command.  Or, better still,
use a Richard's box (doesn't coredump, doesn't waste CPU;
may collapse under its own weight and crush you, though;
therefore not recommended for large proteins and viruses).
Even better: wait until Biosym or Mol. Sim. come with a
user-friendly O-clone ("yesterday's science with today's
user-interface at tomorrow's prices") and spend three
PhD-students' worth of cash on that instead !

See my previous posting for a one-line macro which does just that.
On the other hand, if you can afford it, you should have two
types of machine: graphics and compute engines.  You do not
want to run XPLOR in the background when you use any graphics

First of all, I think it violates "netiquette" to quote from
private E-mails without asking people's permission to do so.
Apart from that, there's a thing called psychology.  Alwyn is
not sitting behind his computer anxiously waiting for requests
for new options and bug reports.  If you send *ANYONE* in
the xtallographic community who develops software which you
(almost) get for free, a mail saying "I am NOT going to use
your program until you implement this or that", what do you
think the response will be (if any) ???
By the way, Alwyn doesn't read Usenet, so he can't defend
himself in this forum.
As for "Alwyn's monopoly":
- originally, O was intended to be his private play-thing;
  it was not intended for world-wide distribution; still,
  no one is forced to use O.  If you rate user-friendliness
  higher than versatility and "state-of-the-art-ness", fine.
- in the case of FRODO, there was no monopoly and source code
  was freely distributed and not copyrighted.  Thanks to this,
  FRODO-off-rippers can now make money by selling their product
  to companies (without paying a penny to Alwyn).  I can't
  blame him for not handing out source code anymore.
