Day-night genes and their associated binomial <i>P</i> value.

For each gene, the number of tissues for which the gene is day or night, for (i) all tissues, (ii) non-brain tissues, and (iii) brain tissues. For each of the previous tissue classification, a binomial P value is associated to test if the gene has a statistically significant preference to be highly expressed during the day or the night. Genes with a P ≤ 0.05 for at least one of the tissue classifications are part of the high-confidence day-night gene sets. Note that for a gene to reach a P ≤ 0.05 it needs to have been identified day-night in at least 6 tissues. See Methods for details. (XLSX)
