IgDiscover analyzes antibody repertoires and discovers new V genes from high-throughput sequencing reads. Heavy chains, kappa and lambda light chains are supported (to discover VH, VK and VL genes).
IgDiscover is the result of a collaboration between the Gunilla Karlsson Hedestam group at the Department of Microbiology, Tumor and Cell Biology at Karolinska Institutet, Sweden and the Bioinformatics Long-Term Support facility at Science for Life Laboratory (SciLifeLab), Sweden.
