Filtering Delly Raw results for Hotspots

Primary LanguagePython

detect_hotspot_sv.py

Look for potential hotspot structural variants by applying filters to all SVs called by DELLY.

Some code adapted from Ronak Shah's check_cDNA_contamination.py.

Usage:

usage: detect_hotspot_sv.py [-h] [-s sample_name] [-t n] [-hsl hotspot_list]
                            [-bl black_list] [-kgl keep_genes]
                            [--iAnnotateSV iAnnotateSV.py]
                            [--genome {hg18,hg19,hg38}]
                            structural_variants.vcf /path/to/output_directory/

positional arguments:
  structural_variants.vcf
                        VCF with deletion event calls
  /path/to/output_directory/
                        Directory to put output in

optional arguments:
  -h, --help            show this help message and exit
  -s sample_name, --sample-name sample_name
                        Prefix [default: filename of in_vcf]
  -t n, --threshold n   Output must have at least this many qualifying PE
                        support. [default: 1]
  -hsl hotspot_list, --hotspotFile hotspot_list
                        path to list of hotspots
  -bl black_list, --blackListGenes black_list
                        path to list of black list genes File
  -kgl keep_genes, --genesToKeep keep_genes
                        path to list of genes to keep file
  --iAnnotateSV iAnnotateSV.py
                        path to iAnnotateSV.py script [default: /home/shahr2/g
                        it/iAnnotateSV/iAnnotateSV/iAnnotateSV.py]
  --genome {hg18,hg19,hg38}
                        Reference genome version to use during annotation
                        [default: hg19]

Example usage:

$ python detect_hotspot_sv.py example.vcf ./ -s my_sample -hsl /path/to/hotspotlist -kgl /path/to/geneToKeep -bl /path/to/blacklist

Output:

  • <output directory>/<sample name>.hotspot_sv_final.txt: a one-line, tab-delimited list of sample name and its structural variants
  • Intermediate files in <output directory>/scratch/

Requires:

Script process

  1. Filter the input VCF for any events occuring i defined hotspots
  2. Convert the filtered VCF to tab-delimited input format for iAnnotateSV, using iCallSV.dellyVcf2Tab
  3. Annotate using iAnnotateSV
  4. Merge Annotation with VCF with iCallSV.mergeFinalFiles
  5. Filter merged files with iCallSV.fiterAnnotatedSV
