Supplementary Figure 2: Boxplots of 100 realizations of the SC3 clustering on the Deng, Pollen and Kolodziejczyk datasets.

For clarity, lines are drawn through the medians of the boxplots. The x-axis shows the number of eigenvectors d of the transformed distance matrix as a percentage of the total number of cells N in each dataset. The black vertical lines correspond to d = 4% of N and d = 7% of N. Dots represent outliers that are higher than the highest value (or lower than the lowest value) within 1.5 * IQR, where IQR is the inter-quartile range, or distance between the first and third quartiles.
