Comparison between 1-dimensional and 2-dimensional modules in gastric cancer. (A) Horizontal axis represents BP categories ranked by their depths in the BP ontology. Vertical axis represents CC categories ranked by their depths in the CC ontology. The thick blue lines represent the 1-dimensional modules and the red squares represent the 2-dimensional modules. (B) In the confusion matrix, we show the numbers of BP categories which are present in both 1-dimensional and 2-dimensional modules; present in 1-dimensional but absent in 2-dimensional modules; absent in 1-dimensional but present in 2-dimensional modules.
