print_world_values

evaluate volume values at multiple world coordinates from a file

print_world_values <glimfile> <coordlist file> <outputfile>

DESCRIPTION

print_world_values reads world coordinates from a coordinate list file and evaluates the volumes listed in a glim (general linear model) file at those positions. The results are written to the output file.

The glimfile contains a list of MINC volume filenames. The coordlist file contains a list of world coordinates (one set of x, y, z per line). For each coordinate, the program evaluates every volume in the glimfile and writes the values to the output file.

This is useful for extracting values at specific anatomical locations across multiple volumes, such as in statistical analyses.

EXAMPLES

print_world_values volumes.glim coordinates.txt output.txt
