Cluster_Unifrac

Run R package GUnifrac (https://cran.r-project.org/web/packages/GUniFrac/GUniFrac.pdf) in parallel

Description

This script uses the GUniFrac package created by Dr. Jun Chen to separate the calculations of UniFrac distances into multiple jobs. These jobs can be run on a local cluster in parallel. Then the results can be merged back into the full distance matrix.

Usage:

• Obtain the number of rows (n) from the OTU table using script:

Job 1: Rscript run.R 2 .... Job n-1: Rscript run.R n.

• Submit n-1 jobs to cluster.

• After you get n-1 Rdata files then run Load.R to get the full matrix.
