Highlights of the 4.1.4.1 release:

  • New experimental HaplotypeCaller assembly mode which improves phasing, reduces false positives, improves calling at complex sites, and has 15-20% speedup vs the current assembler. It is enabled with option --linked-de-bruijn-graph. This mode is still experimental and not recommended for production use yet.
  • IndexFeatureFile improvements:
    • now cloud enabled
    • changed controversial F argument to I instead.
  • Bug fixes and improvements in GenomicsDB, Mutect2, variant annotation, and more!
