In Extended Data Fig. 4a of this Letter, the ‘JUN’ and ‘AXL’ labels on the histograms were inadvertently switched. The unmodified plot files and R code used to generate this figure are available on the Dropbox repository available with this Letter (link to the plot file: https://www.dropbox.com/s/fl4ungg63rz4mnw/WM9_noDrug_20150810_geneHistogramRugs.pdf?dl=0; link to R code: https://www.dropbox.com/sh/g9c84n2torx7nuk/AABrhqLdqD8jGw7vd1duKXZ6a/paper/plotScripts/RNAFISH?dl=0&preview=RNAFISH_analysis.R). Extended Data Fig. 4a of the original Letter has been corrected, and the original panel is shown as Supplementary Information to this Corrigendum for transparency. In addition, in Extended Data Fig. 9a, the underlying image for ‘SK-MEL-28 NGFR sort biological replicate 2’ was duplicated and also shown for ‘WM989-A6 NGFR sort biological replicate 2’. The overlying colony counts for this dataset were correct. The Dropbox repository available with this Letter contains the correct images for both samples (link for SK-MEL-28 NGFR sort biological replicate 2: https://www.dropbox.com/s/qek7o4l20tob33m/polygonImg_20160602_SKMEL_replicate.eps?dl=0; link for WM989-A6 NGFR sort biological replicate 2: https://www.dropbox.com/s/c0bajc19qfswhgz/polygonImg_20160517.eps?dl=0). Extended Data Fig. 9a of the original Letter has been corrected, and the original panel is shown as Supplementary Information to this Corrigendum for transparency. We thank S. Y. Lee for identifying the duplicated image and bringing it to our attention. The conclusions of this Letter are unaffected by these errors.
