This version of abismal has several improvements over abismal-1.0.0 (described below). Please note that any index built with 1.0.0 must be rebuilt, as they are not compatible with the current release.

List of changes:

  • The new index uses less memory. For hg38, the memory footprint for mapping is reduced from 3.5 GB to 2.7 GB
  • Abismal 2.0.0 now performs full alignments
  • Abismal 2.0.0 has algorithmic guarantees on exact matches. If a read matches the reference genome exactly somewhere, the match is guaranteed to be found.
  • Abismal 2.0.0 is faster in smaller genomes. Search parameters used internally are based on genome k-mer frequencies rather than "hard-coded", which improves speed in genomes like arabidopsis, chicken and bacteria.
  • A documentation is now available describing the SAM output format, a detailed description of each parameter and several examples of use.

Some issues are also resolved relative to the previous version:

  • 9c93354 : resolves an issue where abismal crashes if a long read is passed to it. If a read is larger than 65535, abismal will report an error message
  • the percent_unmapped report now shows 100 minus the percent_mapped (whereas before it showed 100 - percent_unique)
  • the error_rate is no longer a percentage, but rather a fraction
