IgBLAST is a popular NCBI package for classifying and analyzing immunoglobulin (IG) and T cell receptor (TCR) variable domain sequences. We’ve released a new version (1.14.0) of IgBLAST with three new improvements / bug fixes:
- Adaptive Immune Receptor Repertoire (AIRR) format is more consistent with AIRR specs including changing undefined type (NON, N/A) to empty string, not appending “reversed” to sequence identifier when the query is in reversed orientation, and using standard locus names such as IGH, TRB instead of traditional VH, VB etc.
- The logic for showing CDR3 end of TCR sequences is improved.
- The sequence identifier is restored in the case of no results in AIRR rearrangement format.
