 Data Submitters are responsible for running the WDL on their data to generate the QC metrics.  If this workflow is given a threshold file, then it can report QC status outputs directly to the AnVIL data table as additional columns. AnVIL Data Processing Working Group has also created QC aggregator Jupyter notebook. Once QC status criteria have been determined, the thresholds can be modified in the notebook. The criteria is used to assign QC status of pass or fail. If a sample fails multiple times, it is assigned No QC under QC status.

 There is an additional [example JSON for exome](SingleSampleQc.exome.json).  It should have all the inputs necessary to run aside from the input BAM, sample name, and threshold file.  After supplying those inputs, the workflow can be run just as in the WGS case and outputs can simiarly be written to the data table.
