Each row is one gene, each column one RNA-seq sample, and each cell the mean expression of that sample’s group expressed as a z-score across the row: red means higher than that gene’s own average, blue lower. The scale is per row, so colours compare samples within one gene — reading a red cell in one row against a red cell in another tells you nothing about which gene is more abundant. Hover any cell for the full sample name and the underlying z-score.
