Making AIRR format more consistent with AIRR specs including changing undefined type (NON, N/A) to empty string, not appending “reversed” to seqid when query is in reversed orientation, using standard locus names such as IGH, TRB instead of traditional VH, VB etc.
Loosening criteria to show CDR3 end by allowing the first FWR4 base to be missing.
Bug fix: Restoring seqid for no result case in AIRR rearrangement format. Printing IgBlast version number instead of Blast version number with -version option.

- Release 1.13.0
Determine the V gene reading frame from the end of FWR3 region instead of end of V gene. This is to allow proper determination of the frames for rearrangements that have insertions or deletions near the V gene end.
Increase allowed distance between V gene end and J gene start to 225 bp to allow detection of ultra long D/N region.
- Package the edit_imgt_file.pl script, the internal_data and optional_files folders into the IgBlast release such that it is easy for u ser to install.

Increase allowed distance between V gene end and J gene start positions (from 90 bp to 150 bp) as well as between V gene end and D gene start positions (from 55 to 120 bp) to accommodate extremely long VDJ junctions found in some antibodies.

Change the 0-based coordinate system to 1-based coordinate system in AIRR format (with -outfmt 19 parameter) for sequence start positions per the new AIRR Rearrangement Schema ( http://docs.airr-community.org/en/latest/datarep/rearrangements.html ).

Adding the AIRR rearrangement tabular format
Sept 22, 2017
Re-engineered multi-threading mechanism which significantly shortens the processing time. Default t o use 4 threads.
Added ability to accept the SRA accession directly as query input.
Lower the default nucleotide mismatch penalty values for finding D and J genes (from -4 to -2 and f rom -3 to -2, respectively). This is to better accommodate moderately mutated sequences.

- Make nucleotide overlaps at VDJ junctions an option (-allow_vdj_overlap) and default is set to no o verlap allowed. Previous versions were hard-coded to allow nucleotide overlaps at VDJ junctions. *Use alignment length instead of percent identity as tiebreaker for hits with identical blast scores .
- Allow custom J gene mismatch penalty.
- Add CDR3 start and stop to sub-region table
Oct 26, 2016
- Release 1.6.1
- Added clonotype report
- Enabled multi-threading option -num_threads
April 25, 2016
- Release 1.5.0
- Added CDR3 annotation
- Added option for extending at 5’ side
- Default to IMGT region (was Kabat previously)
July 17, 2014
- Release 1.4.0
- Added capability to analyze monkey sequences.
February 19, 2014
- Release 1.3.0
- Better handling of non-Ig sequences
- Include makeblastdb binary with pre-compiled releases
