+This is a genomics pipeline to do a single germline sample variant-calling, adapted from GATK Best Practice Workflow.

+This workflow is a reference pipeline for using the Janis Python framework (pipelines assistant).
+- Alignment: bwa-mem
+- Variant-Calling: GATK HaplotypeCaller
+- Outputs the final variants in the VCF format.

+**Resources**
+
+This pipeline has been tested using the HG38 reference set, available on Google Cloud Storage through:

+- https://console.cloud.google.com/storage/browser/genomics-public-data/references/hg38/v0/

+The known sites (snps_dbsnp, snps_1000gp, known_indels, mills_indels) should be gzipped and tabix indexed.
