ASAR: visual analysis of metagenomes in R.

Motivation Functional and taxonomic analyses are critical steps in understanding interspecific interactions within microbial communities. Currently, such analyses are run separately, which complicates interpretation of results. Here we present the ASAR interactive tool for simultaneous analysis of metagenomic data in three dimensions: taxonomy, function, metagenome. Results An interactive data analysis tool for selection, aggregation, and visualization of metagenomic data is presented. Functional analysis with a SEED hierarchy and pathway diagram based on KEGG orthology based upon MG-RAST annotation results is available. Availability Source code of the ASAR is accessible at GitHub (https://github.com/Askarbek-orakov/ASAR). Contact [email protected].
