Browsing TCGA paired associations network with grouped links. This network of paired associations for four different GBM subtypes (plus a fifth combined analysis) contains over 5,000 nodes and 106 edges. The link grouping feature is being used, so that each node typically shows five ordered, distinct edge wedges, one for each of the analyses. The alternating light blue/pink node zone shading feature allows these wedges groups to be associated with the underlying node. In this case, dragging the mouse while holding down the Ctrl (Command on Mac) key, in combination with the network magnifier, provides a simple way to browse the entire network in a linear fashion, looking for interesting patterns between the subtypes.
