## Description

400 samples were sequenced using Illumina NovaSeq 6000 and Illumina HiSeq 2500. The dataset comprises raw sequencing data in FASTQ format and normalized gene counts for all samples. The normalized gene count files include replication, discovery, specificity, and continuum files categorized by CDR levels.
