Tab A. The loadings of all metagenes across brain development stages in the analysis of the BrainSpan dataset.

The table shows that the loading of the 5th metagene for the early-mid fetal stage (the 5th stage) is highly positive, and its absolute value is much larger than that of the metagene for other developmental stages. Thus, the 5th metagene can be used to characterize the stage. Tab B. The loadings of all metagenes across all brain regions in the analysis of the BrainSpan dataset. The table shows that the loading of the 1st metagene for the striatum is highly positive, and its absolute value is much larger than that of the metagene for other brain regions. Thus, the 1st metagene can be used to characterize the brain region. (XLSX)
