# FACETS QC criteria

Starting with `v2`, the `facets QC` is versioned independent of the `facets-preview`. The version # is also logged (with column `facets_qc_version`) in `facets_qc.txt` and `facets_review.manifest`.

## v1.0&#x20;

*TODO: add more details*

1. Too low fraction of the genome diploidy (2-0 or 1-0)
2. `dipLogR` is too high (high homdels)
3. `dipLogR` is too low (high ploidy)
4. High `ploidy` filter
5. Hypersegmentation
6. Fragment size difference between T/N ("waterfall")
7. Invalid purity (`purity` = 0.3 or NA)
8. Large discordance in TCN between EM and CNCF
9. Too large fraction of genome subclonal
10. Discordance between integer copy number and `logOR`.
11. Contamination filter (homozygous SNPs)

## v0.0

Initial version of facets QC.&#x20;
