a) Sample ID: Sample number. b) Raw: Raw reads, the number of original sequences from the original image data obtained by sequencing and converted by base calling. c) Clean: Clean reads, raw reads were removed from the adaptor sequence and low-quality bases, and the number of effective sequences was used for subsequent analysis. d) Clean Per: the proportion of Clean reads in raw reads. e) Unique tag: Unique tag, number of non-repeat reads and proportion of clean reads.
