idfprocess(1)               General Commands Manual              idfprocess(1)



NAME
       idfprocess - do operations on and get statistics from distortion fields

SYNOPSIS
       idfprocess [options] input_file(s) output_file

DESCRIPTION
       Idfprocess will do several simple operations on image distortion field
       files: it can compute the inverse of the fields in one file, or the
       product or difference of fields in two files, and it can report statis-
       tics on the vectors of each distortion field.

       If a product or difference is taken, two input files are required, but
       the output file is optional.  If an inverse is taken, only one input
       file is expected, and again the output file is optional.  In either
       case, if no output file is specified, the program will reports statis-
       tics on the output automatically.  If no operation is performed, sta-
       tistics will be reported for the fields in the input file.

       For products and differences, if one file has one field and the other
       has more than one, the single field will be combined with each of the
       fields in the other file.  If both files have more than one field,
       there must be the same number of fields in both files, and correspond-
       ing pairs are combined to produce the same number of fields in the out-
       put.

OPTIONS
       Idfprocess uses the PIP package for input exclusively (see the manual
       page for pip).  The following options can be specified either as
       command line arguments (with the -) or one per line in a command file
       (without the -).  Options can be abbreviated to unique letters; the
       currently valid abbreviations for short names are shown in parentheses.

       -in1 OR -InputFile1       File name
              First input file with distortion fields.  If this option is not
              entered, the first non-option argument will be used for this
              input file.

       -in2 OR -InputFile2       File name
              Second input file with distortion fields.  If this option is not
              entered and a second input file is expected, the second non-
              option argument will be used for this input file.

       -output (-o) OR -OutputFile    File name
              Output file for processed distortion fields.  If this option is
              not entered, the second or third non-option argument will be
              used for the output file, depending on whether one or two input
              files are required.  If no output file is specified at all, then
              statistics will be computed.

       -product (-p) OR -Product
              Compute product of two distortion fields

       -difference (-d) OR -Difference
              Compute difference between two distortion fields

       -inverse (-inv) OR -Inverse
              Compute the inverse of the distortion field

       -stats (-st) OR -Statistics
              Report mean, SD, and max of distortion vectors

       -second (-se) OR -SecondGrid
              If the grid characteristics (spacing and number of grid points)
              differ between the two files, convert to the second file's char-
              acteristics rather than the first.

       -help (-h) OR -usage
              Print help output

       -StandardInput
              Read parameter entries from standard input.
