NAME
       onepatchcorr - Correlate a patch from two volumes at one position

SYNOPSIS
       onepatchcorr xsize ysize zsize  xcen ycen zcen  filea fileb  out-
       put_file

DESCRIPTION
       onepatchcorr will determine the 3-D displacement between a single sub-
       set or patch extracted from two image volumes in filea and fileb.  It
       extracts the patch from each of the two volumes using tapervoledge.  It
       then uses clip to do 3-D cross-correlation between the patches and
       determines the displacement of the patch in fileb relative to the patch
       in filea.  It writes a single line to the output file giving the dis-
       placement between the two files in X, Y, and Z.


ARGUMENTS
       The size of the patch in X, Y, and Z is set by the arguments xsize,
       ysize, and zsize.

       The location of the center of the patch is given by the index coordi-
       nates xcen, ycen, and zcen.
