match_tags

find corresponding tag points between two tag files

match_tags [options] infile1.tag file2.tag outfile2.tag

DESCRIPTION

match_tags finds corresponding tag points between two tag files. For each tag in infile1.tag, the program searches file2.tag for the closest tag point within the maximum allowed distance. Matched tags from file2.tag are written to outfile2.tag in the same order as the tags in infile1.tag.

This is useful for establishing point correspondences between two sets of anatomical landmarks, such as when comparing tag points identified in different scans or by different raters.

OPTIONS

-max_distance distance

Maximum distance for two tag points to be considered a match. Default: 3.4e38 (effectively unlimited).

EXAMPLES

match_tags scan1.tag scan2.tag matched.tag

match_tags -max_distance 5.0 scan1.tag scan2.tag matched.tag
