What we're currently using:

1) TOM/FRODO

   Contact:  Christian Cambillau

   Address:
      Laboratoire de Cristallographie
      Faculte' de Me'decine Nord
      Boulevard Pierre Dramard
      13326 Marseille cedex 15
      France

   Phone:
      33-91.65.79.47

   Fax:
      33-91.65.75.95

   Licence fee:
      2000 French francs

   TOM/FRODO is shipped with source code.  (The source code is a
   mess, though).  There is a "fixed up" version of this program
   with mods by Gary Griffin of SGI and by me.	For details, send a
   message to "frodo-request at sgi.com".

Coming "real soon now":

2) TURBO-FRODO

   Contact:  Christian Cambillau

   Address, phone:  as above

   Licence fee:
      U.S. $1000 to $2000 (depending on machine model) for
      academic users.  10 times as much for commercial users.

   Source code is not available.  The beta-test version we have
   has many regressions from our fixed version of TOM/FRODO
   (e.g. there's no way to translate the model on the screen).
   These MAY be fixed in the next release.

3) CHAIN

    Contact:  John Spurlino

    Address:
       Baylor College of Medicine
       Texas Medical Centre
       One Baylor Plaza
       Houston, Texas 77030
       U.S.A.

    Phone:
       (713) 798-6563

    E-mail:
       jcs at DINO.QCI.BIOCH.BCM.TMC.EDU

    Licence fee:
       not yet known.  We got a free licence for one year.

    CHAIN is the best map-fitting program we've yet seen.  The
    general policy will be not to release source.  Currently
    there's nothing to skeletonize maps.

4) O
   (Yes, that's right, it's called "O".)

   Contact:  Alwyn Jones

   Address:
      Dept. of Molecular Biology
      Biomedical Center, Uppsala University
      Box 590
      S-751 24 Uppsala
      Sweden

   Phone:
      018-174566

   E-mail:
      ALWYN at BMC.UU.SE

   Licence fee:
      Probably around $250.  For academic users only.  The contract
      threatens a lawsuit if a commercial user gets ahold of it.

   We haven't even seen the test version of this yet, but we
   expect it in the next few weeks.  Source will not be released.
