Workflows used for germline short variant discovery in WGS data
This repository has been deprecated in favor of https://github.com/gatk-workflows/gatk4-genome-processing-pipeline
This WDL pipeline implements data pre-processing and initial variant calling (GVCF generation) according to the GATK Best Practices (June 2016) for germline SNP and Indel discovery in human whole-genome sequencing data.
- Human whole-genome paired-end sequencing data in unmapped BAM (uBAM) format
- One or more read groups, one per uBAM file, all belonging to a single sample (SM)
- Input uBAM files must additionally comply with the following requirements:
-
- filenames all have the same suffix (we use ".unmapped.bam")
-
- files must pass validation by ValidateSamFile
-
- reads are provided in query-sorted order
-
- all reads must have an RG tag
- Reference genome must be Hg38 with ALT contigs
- Cram, cram index, and cram md5
- GVCF and its gvcf index
- BQSR Report
- Several Summary Metrics
- GATK 4.0.10.1
- Picard 2.16.0-SNAPSHOT
- Samtools 1.3.1
- Python 2.7
- Cromwell version support
- Successfully tested on v37
- Does not work on versions < v23 due to output syntax
- The provided JSON is meant to be a ready to use example JSON template of the workflow. It is the user’s responsibility to correctly set the reference and resource input variables using the GATK Tool and Tutorial Documentations.
- Relevant reference and resources bundles can be accessed in Resource Bundle.
- Runtime parameters are optimized for Broad's Google Cloud Platform implementation.
