From: IDTAXA: a novel approach for accurate taxonomic classification of microbiome sequences
Confidences assigned to random and repeat sequences. Using the RDP training set, the RDP Classifier and SINTAX assigned high confidences at the domain level (i.e., Bacteria or Archaea) to 1000 query sequences composed of 1000 random nucleotides. Similarly, both the RDP Classifier and SINTAX assigned high confidence at the genus level to 1000 sequences composed of repeats with periodicity varying from 1 (e.g., AAA...) to 7. In contrast, the IDTAXA, MAPSeq, and SPINGO algorithms assigned low confidences to random and repeat sequences at all taxonomic levels
