dissimilarity_mtx_stats.py – Calculate mean, median and standard deviation from a set of distance matrices

Description:

This script reads in all (dis)similarity matrices from an input directory (input_dir), then calculates and writes the mean, median, standdard deviation (stdev) to an output folder.

The input_dir must contain only (dis)similarity matrices, and only those you wish to perform statistical analyses on.

Usage: dissimilarity_mtx_stats.py [options]

Input Arguments:

Note

[REQUIRED]

-i, --input_dir

Path to input directory

-o, --output_dir

Path to store result files

Output:

The outputs are in distance matrix format, where each value is the mean, median, or stdev of that element in all the input distance matrices

Example:

This examples takes the “dists/” directory as input and returns the results in the “dist_stats/” directory:

dissimilarity_mtx_stats.py -i dists/ -o dist_stats/
