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.
