XDRAW available for SGI



              XDRAW 1.1 IS NOW AVAILABLE FOR THE SGI
      Professor Douglas A. Smith and the University of Toledo
                announce the availability of their
               Software Tools for Molecular Modeling
 FITIT version  3.0 is  a question  and answer  driven file format
 conversion program.   It  will read  output files from MacroModel
 (formatted, unformatted,  and DUMPCT),  MM2, MM3, MOPAC and AMPAC
 and convert  them to input files for MacroModel, MM2, MM3, MOPAC,
 AMPAC, XDRAW  and ARKMOD.   Handling  of multiple structures in a
 single file  is supported,  and users may edit atom types for one
 or all  structures on  the fly.  Interfaces to Gaussian 88/9x are
 under development and should be available fourth quarter of 1991.
 FITIT is  written in  machine independent FORTRAN 77 and has been
 successfully run  under VMS,  UNIX (several  variants), and  DOS.
 FITIT is  available for  a per  machine price  of $250,  or  site
 licensed for only $800.
 XDRAW version  1.1 is  an X11  compatible version  of the popular
 DRAW program,  written by Maj. D. Storch of the USAF.  Originally
 designed for  use with  MOPAC, the combination of XDRAW and FITIT
 will now  let you  visualize, analyze,  and plot input and output
 from a variety of molecular modeling packages.  XDRAW runs on any
 UNIX or VMS machine, and can be displayed across a network to any
 X-windowing environment.   The  X11 graphics  have been tested on
 DECstations and VAXstations under DECWindows, SUN, HP series 700,
 Apollo DN  series, Stardent and now on all SGI workstations (users
 eithre need the Xwindow Developer's Kit from SGI in order to
 compile XDRAW on their machine or can obtain an executable from
 Dr. Smith).  XDRAW is also Motif compatible.  The code  is machine
 independent FORTRAN  77 and  C.   XDRAW  is available for  a per
 machine price of $100, or site licensed for only $300.
 BOLTZMAN  version   1.0  is   designed  to  calculate  ratios  of
 components and  DDG values  of a  collection of  molecules.   The
 program will  accept input  in the form of answers to a series of
 questions from  the screen  or an  input file,  and includes both
 novice  and  expert  modes.    BOLTZMAN  is  written  in  machine
 independent FORTRAN 77, and has been run under VMS, UNIX (several
 variants), and  DOS.   BOLTZMAN is  available for a site licensed
 price of only $25.
 !SPECIAL DEAL!  Site license all three programs for only $975.
