Summarize¶
The summarize command adds new INFO fields and FORMAT tags that combine variant data from the merged VCF. It will only work with VCF files that have been translated.
Usage¶
$ jacquard summarize <input_file> <output_file>
positional arguments:
input_file | Jacquard-merged VCF file (or any VCF with Jacquard tags; e.g.
JQ_SOM_MT)
|
output_file | A single VCF file
|
Description¶
The summarize command uses the Jacquard-specific tags to aggregate caller information from the file, providing a summary-level view. Summary fields (e.g. average allele frequency) can highlight interesting variants.
The summarized format tags contain the prefix ‘JQ_SUMMARY’.
Example summary FORMAT tags¶
Tag name | Description |
---|---|
JQ_SUMMARY_AF_AVERAGE | Average allele frequency across recognized variant
callers that reported frequency for this position
[average(JQ_*_AF)].
|
JQ_SUMMARY_AF_RANGE | Max(allele frequency) - min (allele frequency)
across recognized callers.
|
JQ_SUMMARY_HC_GT | High confidence consensus genotype (inferred from
JQ_*_GT and JQ_*_CALLER_PASSED). Majority rules;
ties go to the least unusual variant (0/1>0/2>1/1).
Variants which failed their filter are ignored.
|
JQ_SUMMARY_SOM_COUNT | Count of recognized variant callers that reported
confident somatic call for this sample-position.
