Principal component clustering of RNA-seq libraries

The three-dimensional principle component analysis (PCA) plot of 92 RNA-seq libraries was generated based on the 750 most variable genes, showing the highest variance in expression between time points in all samples. While all libraries clustered very well together according to their tissues, no clear distinction regarding different age groups could be made. PCA plots of each tissue based on different sets of genes are available at https://osf.io/ru2sb/, showing in general always the same clustering.
