prepon

Generate an index for a PON file. This is a prerequisite for using the "--pon" option in mutectcaller.

prepon requires that the Contig field be present in the header of the input .vcf.gz file in order to do memory allocation at the start of execution. This field should include both the chromosome name and length:

Copy
Copied!
            

##contig=<ID=chr1,length=248956422> ##contig=<ID=chr2,length=242193529> ##contig=<ID=chr3,length=198295559> ...

If your input .vcf.gz file does not include these value, run this command to update the header before running prepon:

Copy
Copied!
            

$ bcftools reheader --fai YOUR_REFERENCE_FILE.fa.fai INPUT_PON.vcf.gz > UPDATED_PON.vcf.gz

Copy
Copied!
            

# This command assumes all the inputs are in INPUT_DIR and all the outputs go to OUTPUT_DIR. docker run --rm --gpus all --volume INPUT_DIR:/workdir --volume OUTPUT_DIR:/outputdir \ --workdir /workdir \ nvcr.io/nvidia/clara/clara-parabricks:4.3.1-1 \ pbrun prepon \ --in-pon-file /workdir/${INPUT_PON_VCF}

Build the index for a PON file; this is a prerequisite for mutect pon
