New releases from NCBI: IgBLAST 1.7.0 and Sequence Viewer 3.21

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.

Sequence Viewer 3.21

Sequence Viewer 3.21 has several new features, improvements and bug fixes, including improved track hiding, and parameters to define pile-up praph size in BAM files (demo).For a full list of changes, see the Sequence ViewerĀ release notes.

Sequence Viewer is a graphical view of sequences and color-coded annotations on regions of sequences stored in the Nucleotide and Protein databases.
