Statistical analysis for marker gene studies


This tool produces several visualizations (rarefaction and rank-abundance curves and an RDA plot), and compares the diversity between groups of samples using several ANOVA-type of analyses. It also performs indicator species analysis and contribution diversity approach.



This tool takes two input files: a count table that contains the counts of the identified species or operational taxonomic units (OTUs) in each sample, and a phenodata table that describes the grouping of the samples. Statistical tests only work for datasets which contain 2-3 groups. The analyses are based on the functionality of the R packages vegan, rich, biodiversityR, pegas and labdsv.
