OTU clustering outputs

The OTU clustering tool produces several outputs: a sequence list of the OTU centroids, and two abundance tables with the newly created OTUs and chimeras.

In the OTU merge report - generated if the input reads were paired - the following statistics are given for each sequence list input in the tool: a summary of merged and non-merged sequences, an alignment score distribution and a merged pairs length distribution.

The tool also produces a report (figure 5.5).
