Basic information or PNM images.
|
man/fiinfo

A set of files containing the transposed tabulated data or a single file for the statistics, also in a tabulated form.
|
man/grcollect
|
| grmatch
|
Matches lines read from two input files of tabulated data, using various criteria (point matching, coordinate matching or identifier matching).
|
Two files containing tabulated ASCII and/or numeric data (that must be two point sets in the case of point or coordinate matching).
|
One file containing the matched lines and in the case of point matching, an additional file that describes the best fit geometric transformation between the two point sets.
