Warehouse Workflow Spotlight: Part 3

Apr 14, 2026

Many labs already use DRAGEN upstream, but want more control over what happens after variant calling is complete. VSWarehouse 3 connects those outputs to downstream tertiary workflows that labs can automate, configure, and adapt to their own interpretation and reporting process. Using DRAGEN with VSWarehouse 3: A Better Path to…
