Genomics pipelines. At scale. With Spark and Glow. :exploding_head:

What's inside?

Spark based pipelines for:

• Variant calling (built on GATK's HaplotypeCaller)
• Somatic variant calling (built on MuTect2)
• Joint genotyping (built on GenotypeGVCFs)

Building and testing

1. Clone the repo
2. Unpack the big test files archive located in the project root

• tar -xf big-files.tar.gz

3. sbt test

Running on a Databricks cluster

1. Create an init script to download the reference genome from cloud storage (see hls.sh or prepare_reference.py for inspiration.
2. Build an uber jar (sbt assembly)
3. Create a cluster with the init script from step 1 and attach the assembly jar.
4. Run the desired pipeline using one of the attached notebooks.
