grinchbones

NAME

     grinchbones - convert a GRINCH ASCII format  file  to  a  vu
     file

USAGE

     grinchbones < grinch.ASCII > xfit.vu

DISCUSSION

     The input is a University of  North  Carolina,  Chapel  Hill
     Graphics Lab GRINCH ASCII format file (made with the command
     ASCII save filename in interp or use  the  ASCII  option  in
     mkskel)  and  the output is an xfit vu file. The output uses
     the standard GRINCH color scheme for interpreted edges (i.e.
     main chain is green, side chain is violet, etc.) except that
     unknown edges are colored in bins of density  from  blue  to
     red (the same as the default color scheme for the 1st map in
     xfit). This can be used as a background guide  for  building
     the  model  in xfit. Contours can be used for close-up views
     and detailed fitting and ridge lines can be used for  larger
     views  allowing  a  larger portion of map to be viewed since
     ridge lines require fewer lines than contours.

     The coloring scheme is close to that of GRINCH's except  for
     unknown edges:

               M (main)                 green
               B (bridge)               brown
               S (side)                 purple
               O (carbonyl)             red
               F                        cyan
               G                        yellow
               R (residue)              blue
               U (unknown)              0-14 blue, 15-28 purple, >28 orchid
