This pipeline provides several useful tools for analysis of immune repertoire sequencing data. Its main feature is the ability to use information from unique nucleotide tags (UMIs, see this paper for details), which are attached to molecules before sequencing library preparation and allow to backtrack the original sequence of molecule. UMIs make it possible to computationally filter nearly all experimental errors from resulting immune receptor sequences. This pipeline was designed for libraries sequenced using Illumina MiSeq and HiSeq and the main requirement for sequencing reads is that they should contain the entire CDR3 region of immune receptor gene. Sequencing libraries with high over-sequencing, i.e. ones that have 5+ reads per starting molecule (unique UMI tag), should be used for optimal error elimination.
