Fig. 4From: Empirical assessment of the impact of sample number and read depth on RNA-Seq analysis workflow performanceLiterature survey of RNA-Seq experiment sample numbers. Violin plots of sample numbers used in 200 studies containing RNA-Seq differential gene expression analysis, either from all species (a) or limited to primary human samples (b). Individual dots represent average sample number used in each study. Grey dashed line represents six samplesBack to article page
