Ribosomal RNA read cleaning process outcome.

Venn diagrams depicting (A) the initial sorting of rRNA reads and non-rRNA reads with numbers referring to rRNA reads and virus reads in the two bins. The intersection are rRNA-virus chimeric reads. (B) The rRNA reads recognized as chimeric (<90% rRNA) and the resulted cured virus reads after ZWA. The intersection are the remaining rRNA-virus chimeric reads. (C) The rRNA reads recognized in the second round as chimeric (<90% rRNA) and the resulted cured virus reads after ZWA. The intersection are the discarded remaining rRNA-virus chimeric reads.
