Bugfix release, some enhancements Bugfixes - Fix use of regular expressions for CDR3 identification - Fix insertion of IgBLAST score and E-values into the database - Fix loss of sequences with long CDR3 and a mutated end-of-CDR3 motif [note 1] - Fix tag correction routine for large mouse matrix - Fix handling of empty lines in metadata file Enhancements - More economic handling of database connections (includes time-outs) - Remove unused (and unsafe) authentication options - Add alternative CDR3 motifs to config - Add script for repetitive testing of pipeline - Further unification of log output Notes [1] Previous maximum length of CDR3 was 22 amino acids [aa], otherwise the a assignment would fail if (and only if) an alternative end-of-CDR3 motif was used by a sequence. This length limit has now been extended (CDR3 plus J sequence 155 bp). Note that IgBLAST currently (version 1.4.0) has a hard-coded maximum V_end to J_start distance of 89 bp, which should constitute the lower limit of the two.
