IntensityRankSumAnnotator tool is used to perform in-silico validation of Copy Number Variants (CNVs) in the UKBB dataset using SNP array intensity data.
- A Google Cloud account.
- A workflow execution system supporting the Workflow Description Language (WDL), such as:
- Cromwell (v36 or higher). A dedicated server is highly recommended.
- cromshell for interacting with a dedicated Cromwell server.
- Directory path with bed files containing UKBB gCNV output (per chromosome).
- VCF header template
- List of UKBB SNP array files in VCF format:
- List of samples on which to run GenomeStrip IRS
The main scripts to run this analysis are:
ukbbValidation.wdl: this workflow reformats SNP array and gCNV data from the UKBB and calls GenomeStrip IRS for in-silico CNV validation.genomeStripIRS.wdl: runs GenomeStrip IRS and can be executed on its own.
