Fig. 6From: Granatum: a graphical single-cell RNA-Seq analysis pipeline for genomics scientistsProtein–protein interaction network and pseudo-time construction steps. a The PPI network derived from the DE results between PDX primary and metastasized cells in the K-dataset. The color on each node (gene) indicates its Z-score in the differential expression test. Red and blue indicate up- and down-regulation in metastasized cells, respectively. b The pseudo-time construction step. The Monocle algorithm is customized to visualize the paths among individual cells. Sample labels from the metadata are shown as different colors in the plotBack to article page
