onepatchcorr(1) General Commands Manual onepatchcorr(1) 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 is a C-shell script to determine the 3-D displacement between a single subset 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 displacement 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.
