T-cell repertoire annotation and motif discovery tutorial
This tutorial provides a basic introduction to the inference of T-cells specific to certain epitopes and T-cell receptor sequence motif extraction from high-throughput sequencing data (RepSeq). The users will get familiar with VDJdb and VDJtools software and learn some tricks for working with TCR sequences and TCR sequence motifs in R.
