Extended Data Fig. 2: Quality control metrics of scRNA-seq.

a-d, QC Violin plots showing the number of UMIs (top row), genomic features (middle row) and percentage of genes encoded by the mitochondrial genome expressed in each cell cluster (bottom row), UMAP projections after integration and barplots indicating contribution in terms of numbers of cells from each replicate, for each dataset: a, retina b, adult optic lobe c, hatchling optic lobe d, non-optic lobe brain control.
