Sample reproducibility. a Principal Component Analysis (PCA) was performed based on differentially expressed genes (p < 0.05) to obtain an overview for the three conditions (AD, CRM, CF) on gene expression. The PCA scatter plot showed that the three groups (AD, CRM, CF) is the best separation and formed three distinct clusters. b Heat map of sample distance based on Jensen Shannon entropy over gene counts. The result showed three groups were able to be separated
