An anonymous post on PubPeer suggested that the WT and cnr1 heterozygous images of embryos in Fig. 1C were much more similar than expected. The authors contacted us with the original data and the metadata clearly show that the images shown were taken in the same imaging session, but at different time points. However, the authors cannot completely exclude the possibility that these could be images of the same fish. Since they imaged multiple fish per condition (n=11) and included quantification of liver size across samples in Fig. 1D, they are confident in the conclusions stated and were able to supply a replicate image for the cnr1 heterozygous embryo. The corrected panel is shown here and the authors apologise for any inconvenience caused.
