diff_mahalanobis

compute the difference in Mahalanobis distances between two groups

diff_mahalanobis avg1.obj variance1.txt avg2.obj variance2.txt output

DESCRIPTION

diff_mahalanobis computes the difference between two Mahalanobis distance maps derived from two mean surfaces with their associated per-vertex variances. Each group is described by a mean surface object file and a corresponding text file of per-vertex variance values. The resulting per-vertex difference in Mahalanobis distances is written to the output file.

OPTIONS

This tool uses positional arguments only. There are no named options.

avg1.obj
The mean surface object file for the first group.
variance1.txt
A text file containing per-vertex variance values for the first group.
avg2.obj
The mean surface object file for the second group.
variance2.txt
A text file containing per-vertex variance values for the second group.
output
The output file containing the per-vertex difference in Mahalanobis distances.
