Detects clusters of features using omics data and scores metadata (resolution score) based on their influences in clustering. The similarity of features within each cluster can be different (different resolution). Resolution of similarity score takes to account not only similarity between measurements and also the structure in a hierarchical structure of data and number of features which group together.

Create a batch input file (e.g. m2clust.sh). For example:

#!/bin/bash
set -e
module load m2clust
m2clust \
    -i m2clust_demo/synthetic_data/adist.txt \
    -o demo_output \
    --metadata m2clust_demo/synthetic_data/metadata.txt \
    --plot

Submit this job using the Slurm sbatch command.

sbatch [--cpus-per-task=#] [--mem=#] m2clust.sh

Create a swarmfile (e.g. m2clust.swarm). For example:

m2clust -i adist1.txt -o output1 --metadata metadata1.txt --plot
m2clust -i adist2.txt -o output2 --metadata metadata2.txt --plot
m2clust -i adist3.txt -o output3 --metadata metadata3.txt --plot
m2clust -i adist4.txt -o output4 --metadata metadata4.txt --plot

Submit this job using the swarm command.

swarm -f m2clust.swarm [-g #] [-t #] --module m2clust
