IgBLAST 1.9.0 supports the adaptive immune receptor repertoire (AIRR) standard for sequence analysis results. The AIRR format is available on web IgBLAST as well as in the standalone IgBLAST tool, with the -outfmt 19 option.

Supporting this new schema in IgBLAST will enhance the increasing amount of repertoire studies that use next-generation sequencing technology to generate very large sets of Ig/T-cell receptor rearrangement analysis data.

IgBLAST facilitates the analysis of immunoglobulin and T cell receptor variable domain sequences. Get IgBLAST on FTP. A new manual is on GitHub.

IgBLAST 1.7.0 release

A new version of IgBLAST is now available on FTP, with the following new features:

  1. Specify whether overlapping nucleotides at VDJ junctions are allowed in matching V, D, and J genes.
  2. Set a custom J gene mismatch penalty
  3. Report the CDR3 start and stop positions in the sub-region table
  4. Use alignment length instead of percent identity as the tie-breaker for hits with identical blast scores, improving accuracy in the V, D, J gene assignment.

IgBLAST was developed at the NCBI to facilitate the analysis of immunoglobulin and T cell receptor variable domain sequences.
