Huge volume of whole-genome metagenomic samples in repositories keeps growing at increasing pace. In community of researchers, there is a need for robust data analysis tools that allow efficient description of composition, classification and clustering coupled with comprehensive visualization of results Particularly, human gut microbiome is one of extensively studied topics in metagenomic research.We developed a software pipeline for bioinformatic analysis of metagenomic data obtained from human gut microbiota sequencing currently available as a free web service MALINA.
