group_diff
compute group differences and F-statistics from surface data files
group_diff output.f_stat [1] [-t] file1 file2 + file3 file4 ..
DESCRIPTION
group_diff computes group differences and F-statistics from per-vertex surface data files. Two groups of files are separated by a + delimiter. The resulting per-vertex F-statistic values are written to the output file. The optional 1 flag modifies the output format, and the -t flag may be used to select an alternative test statistic.
OPTIONS
This tool uses positional arguments only. There are no named options.
output.f_stat- The output file containing per-vertex F-statistic values.
1- Optional flag to modify the output format.
-t- Optional flag to select an alternative test statistic.
file1 file2 ...- Per-vertex data files for the first group.
+- Delimiter separating the two groups.
file3 file4 ...- Per-vertex data files for the second group.
EXAMPLES
Compute F-statistics between two groups:
group_diff result.f_stat group1a.txt group1b.txt + group2a.txt group2b.txt
