Fork Purpose:

Added index input to several tasks that require them, but for some reason did not have any, which lead to workflow failing. Changed import of tasks to local instead of https://... See commit: 0e689abeea58fe03768bd82cbdb15e7113f5f374


gatk4-exome-analysis-pipeline

Purpose :

This WDL pipeline implements data pre-processing and initial variant calling according to the GATK Best Practices for germline SNP and Indel discovery in human exome sequencing data.

Requirements/expectations :

  • Human exome 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
  • GVCF output names must end in ".g.vcf.gz"
  • Reference genome must be Hg38 with ALT contigs
  • Unique exome calling, target, and bait .interval_list obtained from sequencing provider. Generally the calling, target, and bait files will not be the same.

Output :

  • Cram, cram index, and cram md5
  • GVCF and its gvcf index
  • BQSR Report
  • Several Summary Metrics

Software version notes :

  • GATK 4 or later
  • Cromwell version support
    • Successfully tested on v44
    • Does not work on versions < v23 due to output syntax
