urf2xfit

NAME

     urf2xfit - convert an XENGEN urefls file to a  vu  file  for
     display in xfit.

USAGE

     urf2xfit [urefls]  [xfit.vu]

DESCRIPTION

     If no files are given,  then  the  program  uses  stdin  and
     stdout; if one name is given, then that file is converted to
     stdout.

ENVIRONMENT

     CRYSTAL is the crystal file. It is used to get the unit cell
     for  scaling  the  axes. The present version does not handle
     non-orthogonal space-groups correctly  but  always  displays
     h,k and l as orthogonal axes. Still, this may be useful.

PURPOSE

     By converting a urefls file to a vu file it can be displayed
     in three dimensions with xfit. The three axes H,K, and L are
     displayed as well as a jack at the position of each  reflec-
     tion.  Data  that is missing becomes apparent as well as the
     curved nature of Ewald sphere which is  often  neglected  in
     data collection strategies. Each run can be turned into a vu
     file and displayed in a different color (using the  recolor-
     ing  option  in  xfit) to see how multiple runs overlap. The
     output is colored in 4 bins of intensity from  min  to  max:
     blue, cyan, yellow, white. The color scheme needs expanding,
     and coloring by phi value would be useful.

VERSION
