Fold difference filter

This filter can be added to Default Somatic Variants view filter chains in the software to detect criteria for both copy number depletion (loss) when using the Ion AmpliSeq™ somatic custom CNV analysis workflow or assay.

Filter conditions include the ability to set the CNV fold difference range from 0 to 0.85. In addition, the range boundary values can be included or excluded, and unannotated variants can be included or excluded in filtered analysis results.

The filter returns copy number variants with stringent fold differences and other variants.
