     - Compare all samples to the best, based on above's QC metrics.
     - Check cell type / experiment-specific markers or sex chromosome (`X`/`Y`) for accessibility as positive controls.
     - Check e.g., developmental regions for accessibility as negative controls.

 6. [Unsupervised Analysis](https://github.com/epigen/unsupervised_analysis) (e.g., PCA or UMAP)
     - Identify outliers/drivers of variation, especially in the control samples and within replicates.
