Illustration of spurious node elimination with the GeGUI. a Detail of the extracted graph superimposed onto a detail of the original microscopy image tracheole1 (image in false-colors to improve contrast). b Highlighting of all loops still present in the graph to facilitate elimination of spurious junctions. c The nodes that form spurious junctions can be selected individually by clicking. d Deletion of selected nodes. e The final version of the graph with all spurious junctions corrected and no cycles left
