Analysis Output
When the analysis run completes, the software generates an analysis output in a specified location with the folder name /staging/DRAGEN_Solid_WGS_Tumor_Normal_Pipeline_{version}_Analysis_{datetimestamp}. In ICA, analysis output is listed in the Output section of the analysis, where the folder name is a combination of user reference, pipeline name, and a UUID.
Within the analysis folder, each analysis step generates a subfolder within the Logs_Intermediates folder.

File Overview
This section describes the summary output files generated during analysis.
Metrics Output
The metrics output file is a final combined metrics report that provides sample status, key analysis metrics, and metadata in a tab-separated values (TSV) file. Sample metrics within the report indicate guideline-suggested lower specification limits (LSL) and upper specification limits (USL) for each sample in the run. One metrics output file is generated for the entire run. An additional file is generated for each case.
