Rsem expected counts

WebJun 22, 2024 · Background: In order to correctly decode phenotypic information from RNA-sequencing (RNA-seq) data, careful selection of the RNA-seq quantification measure is critical for inter-sample comparisons and for downstream analyses, such as differential gene expression between two or more conditions. Several methods have been proposed … Webcount转TPM 一、概念 1 raw_count RNA-seq数据中，raw_count一般是指mapped到基因外显子区域的reads数目。比如说htseq，STAR，或者RSEM等NGS分析流程计算产生的counts值。其中RSEM(RNA-Seq by Expectation-Maximization)，考虑到一条read 可能会匹配多个exon位置，故而其产生的为expected_count。
