DRAGEN on-premise via server (All DRAGEN pipelines excluding metagenomics)

Dragen onboard analysis in addition to BaseSpace and server options

  • DRAGEN onboard comes at no additional cost
  • Provides a streamlined workflow for highly accurate secondary analysis with an easy to use graphical interface
  • Generates high quality variant calls directly off of NextSeq 1000 and NextSeq 2000 systems
  • Reduces the need for additional bioinformatics infrastructure and requires fewer touchpoints than other DRAGEN software offerings
