Gene quantification and sample correlation analysis. A Gene expression density distribution of all samples. The x-axis is the logarithm of the expression level (FPKM value) taking base 10, and the y-axis is the density of genes with different expression levels. B Comparison of the degree of dispersion of gene expression levels in different samples. From top to bottom are the maximum value, upper quartile, median, lower quartile, and minimum value. C Principal component analysis of all samples. D Correlation matrix analysis of all samples
