Heatmap of Nematostella vectensis candidate circadian genes across each light treatment a blue, b green, c red, d dark. The experiment key at the bottom of the lower heatmap identifies the ‘photoperiod’ and ‘scotoperiod’ sampling points of the 24-h time course. The columns represent each individual animal that was sampled during the experiment. Three time points were collected during the photoperiod and three time points were collected during the scotoperiod for a total of six collection time points. At each time point, four replicate animals were collected (24 total animals sampled in each treatment; 4 treatments × 6 time points = 96 total animals). Each row of the heatmaps shows expression of a single annotated gene, labelled on the right. The color scale is log2 fold change
