# QC metrics: raw data

In this section, we review quality control (QC) metrics for the **raw feature matrices** generated by `Cellranger`. Only a low level filter excluding cells with <100 nUMIs (= number of unique molecular identifiers, or sequenced reads per cell) was applied when uploading the data into `R`.

# QC metrics: Filtered data

Based on the above QC metrics, we filtered the dataset to isolate cells passing the following thresholds: >`r nCount_RNA_cutoff` UMIs, >`r nFeature_RNA_cutoff` genes, <`r mitoRatio_cutoff` mitochondrial gene ratio, and >`r Log10GenesPerUMI_cutoff` complexity.

In this section, we review QC metrics for our filtered dataset.
