The tests are conducted on each pair of samples present in the input otu table. See the unifrac tutorial online for more details (http://unifrac.colorado.edu/)
Usage: beta_significance.py [options]
The script outputs a tab delimited text file with each pair of samples and a p value representing the probability that a random sample/sequence assignment will result in more dissimilar samples than the actual pair of samples.
Perform 100 randomizations of sample/sequence assignments, and record the probability that sample 1 is phylogenetically different from sample 2, using the unifrac monte carlo significance test. The test is run for all pairs of samples.
