Magic-BLAST 1.3.0: September 15, 2017

New features
  • The alignment cutoff score (-score option) can be expressed as either a constant or a function of read length in this format: L,b,a for a * length + b
  • Maximum edit distance cutoff for alignments can be specified with -max_edit_dist option
  • SRA caching is now turned off by default and can be turned on with the -sra_cache flag. When accessing sequences in NCBI SRA repository the data can be cached in a local file so that it is not downloaded over the network again when reused later. It may result in very large local files and is only needed if you use SRA accessions multiple times, have very limited network bandwidth and a large disk space.
  • Unmapped reads are reported in the SAM and Tabular reports, use -no_unaligned option to not have unaligned reads reported
  • The XS tag (used by transcript assemblers) is now reported in SAM output
  • The score threshold (-score option) now applies to the whole spliced alignment
  • The query batch size (number of reads processed at a time) is now controlled with environment variable BATCH_SIZE expressed in cumulative number of bases
  • The default mismatch and gap extension penalties are now set to 4
  • Improved sensitivity and run time
Bug fixes
  • Read ids for pairs are printed properly in the SAM format (no “.1” “.2” or “/1” “/2”)
  • The secondary alignment bit (256) is set in SAM flags
  • Maximum intron length option -max_intron_length works properly
