OTU97_table_alternative_filtering0.2.unique

A rarefied OTU table (similar to the main OTU table used) using the same dataset but curated with an alternative filtering approach. Once again, to remove any potential water contaminants, we used the blank ‘water’ samples, but instead of creating ‘blank’ OTUs based on the 97% similarity we used the unique sequences. Similarly to the previous filtering approach, we then removed identical sequences that were common in the blank samples and the ant samples if their relative abundances produced an average blank/sample ratio ≥ 0.2.
