New: Now comes in 2 flavors: DB15 and DB12. The '15' flavor creates and uses accelerators intended for very huge databases (think gigabytes) while the '12' flavor creates and uses accelerators suited to smaller (think megabytes) databases.

15 database:
Pros: faster searches, up to 5x faster than DB12 on shotgun.
Cons: larger accelerator size (~4GB larger than DB12), only works for identities ~95% and up

12 database:
Pros: smaller accelerator size, works for identities of 93.5% and up. Great for amplicons
Cons: slower searches (especially on shotgun)

Aside from their respective DB12 or DB15 accelerator formats, everything else is interchangeable between the two variants and both behave identically when used without accelerators.

New in 0.99.3:

  • Much faster searches with accelerator
  • New compressed database and accelerator formats (edx and acx which replace edb and acc respectively)
  • Improvements to output in CAPITALIST mode (some better minpath picks)
  • Much faster query parser and preprocessing for huge shotgun runs
  • Much reduced memory use
  • Introduced "--skipambig" parameter to automatically exclude query sequences with 5 or more ambiguous bases from analysis (serves both QC and speedup role; recommended in most cases)
  • Fixed: mixed memory model for ambiguous queries
  • Fixed: multiline loose-format fasta parser for references (queries still only accept linearized fasta)

Binaries (aka "executables" aka the program itself that you run):

  • Windows and Linux users can use the same binaries now. Windows users must have Windows 10 Creators Update and use the native WSL bash environment.

Older/custom editions may be available upon request (different DB accelerator formats for lower id/smaller accelerators, native Win64 .exe binaries, binaries for older computer processors, etc).
