Path representation and branch switching in the enRoute view. (a) The extracted path from the node EGFR to MTOR is shown top-down along with branches on the left. (b) Expanding the abstract node for leaving branches of EGFR reveals the individual branch nodes PLCG1 and SHC2, which show previews of associated experimental data. (c) By selecting SHC2 the associated branch replaces all path nodes below EGFR. All nodes of the branch are added up to the point where the branch is no longer unambiguous. In this case HRAS represents the end point, as it has two leaving branches.
