Expr_QC. Identification of outlying samples and normalization of RNA-seq based gene expression data. a Gene expression levels of two gender-specific genes: RPS4Y1 and XIST. b The RLE plot before data preprocessing. Aligned box-plots, in increasing order of IQR, represent residuals of gene expression for samples. c Hierarchical clustering of samples before data preprocessing. Color represents the batch of library preparation. d Distribution of D-statistics before data preprocessing. e Hierarchical clustering dendrogram after adjusting batch effects. f The RLE plot after data preprocessing. g Hierarchical clustering dendrogram after data preprocessing
