Additional file 4 of Sequencing introduced false positive rare taxa lead to biased microbial community diversity, assembly, and interaction interpretation in amplicon studies

Additional file 4: Figure S3. Venn diagrams showing the shared OTUs among distinct samples sequenced within the same batch of sequencing run on the Novaseq platform. The large number of shared OTUs among distinct samples (including two customized communities) were likely sample wise cross contaminations caused by index misassignment.
