Fig. 4From: PDAC-ANN: an artificial neural network to predict pancreatic ductal adenocarcinoma based on gene expressionPCA and hierarchical analysis of the merged data set into one data. a. PCA analysis clearly showed two distinct groups corresponding to normal and tumor samples. b. Clustering analysis. The red band indicates the PDAC samples with similar gene expression on 40-core-gene, and the blue band indicates the normal samplesBack to article page
