Description
RSEM is a software package for estimating gene and isoform expression levels from RNA-Seq data. The RSEM package provides an user-friendly interface, supports threads for parallel computation of the EM algorithm, single-end and paired-end read data, quality scores, variable-length reads and RSPD estimation. In addition, it provides posterior mean and 95% credibility interval estimates for expression levels.
Build RSEM references using RefSeq, Ensembl, or GENCODE annotations
RefSeq and Ensembl are two frequently used annotations. For human and mouse, GENCODE annotaions are also available. Here, we show how to build RSEM references using Ensembl annotation. It is important to use every genome version with it’s compatible gtf file.

使用STAR version 2.7.5a及RSEM version 1.3.3 來製作index,請確認已完成GApp standard analysis environment的安裝
#Activate standard analysis environment
conda activate GApp
#移動到工作區(依user設定的工作區而定)
cd /User_Work
#創建放置fasta及GTF的資料夾
mkdir -p refs/Homo_sapiens/GRCh38en102Star2.7.5a/
#移動至資料夾
cd refs/Homo_sapiens/GRCh38en102Star2.7.5a/
