Rarefaction.shared (version 1.39.5.0)

shared - OTU Shared:

label - OTU Labels:

groups - Groups to analyze:

All groups will be analyzed by default if none are selected

run on a per set basis using a design file?:

iters - Number of randomizations:

jumble?:

Obviously, the goal of rarefaction is to randomize across the samples; however, if you just want a collector's curve across the samples you can use the jumble option

calc - Calculators :

produce subsample rarefactions?:

Mothur Overview

Mothur is a comprehensive suite of tools for microbial ecology community. It is initiated by Dr. Patrick Schloss and his software development team in the Department of Microbiology and Immunology at The University of Michigan. For more information, see Mothur-Wiki.

Command Documentation

The rarefaction.shared command generates inter-sample rarefaction curves using a re-sampling without replacement approach. The traditional way that ecologists use rarefaction is not to randomize the sampling order within a sample, rather between samples. For instance, if we wanted to know the number of OTUs in the human colon, we might sample from various sites within the colon, and sequence a bunch of 16S rRNA genes. By determining the number of OTUs in each sample and comparing the composition of those samples it is possible to determine how well you have sampled the biodiversity within the individual.
