The raw data are tags obtained from sequencing without processing. The clean tags are tags that remained after filtering out dirty (low-quality) tags from the raw data. The distinct tags are tags that do not overlap. The unambiguous tags are the clean tags that remained after the removal of tags mapped to reference sequences from multiple genes
