WebApr 1, 2014 · Results: We present featureCounts, a read summarization program suitable for counting reads generated from either RNA or genomic DNA sequencing experiments. … WebMar 30, 2024 · In this paper, we explore the fact that a popular approach in gene-level quantification from RNA-seq data involves mapping reads to a reference genome and then counting mapped reads associated with each gene [1–5]. The process of counting mapped reads to genes requires a database of known genes.
