ImReP is a method for rapid and accurate profiling of the adaptive immune repertoires from regular RNA-Seq data
Download ImReP using
git clone https://github.com/mandricigor/imrep.git
Install ImReP from the base directory
cd imrep
./install.sh
Run ImReP analysis by a single command for the BAM file with mapped and unmapped reads (preferred). BAM file needs to be indexed (.bai file). Forgot to save unmapped reads, we got you covered. Learn more here
python imrep.py --bam example/toyExample.bam example/toyExample.cdr3
Find ImReP analysis in toyExample directory. Learn more here
Use the sidebar on the right to navigate ImReP tutorial. Get started with a toy example of 200 RNA-Seq reads (example/toyExample.bam) distributed with ImRep package
ImReP is a method to quantify individual immune response based on a recombination landscape of genes encoding B and T cell receptors (BCR and TCR). ImReP is able to efficiently extract TCR and BCR reads from the RNA-Seq data and assemble clonotypes (defined as clones with identical CDR3 amino acid sequences) and detect corresponding V(D)J recombinations. Using CAST clustering technique, ImReP is able to correct assembled clonotypes for PCR and sequencing errors.

Using ImReP we have created the Atlas of Immunoglobilin Repertoires (TAIR). The AIR is a collection of CDR3 from Immunoglobulin (Ig) receptor repetoires. CDR3s are assembled from 8,555 human RNA-seq samples across 544 individuals from 53 tissues from the Genotype-Tissue Expression (GTEx v6) project using ImReP.The AIR has one of the largest collection of CDR3 sequences (n=3.6 million) and tissue types (n=53). TAIR is freely available at https://github.com/Mangul-Lab-USC/TAIR
