Parallel coordinates comparison. a) BiVisu parallel coordinates. All gene expression profiles are displayed, with the ones in the bicluster in green and the rest in blue, but only conditions in the bicluster are displayed. The highest and lowest expression levels are hard to tell. b) BicAT parallel coordinates. Gene profiles of the genes in the bicluster are displayed through all the conditions. The conditions in the bicluster are marked by a vertical line, but they are not rearranged, so visual interpretation of the bicluster is difficult. Gene profiles not in the bicluster are not drawn, and no interaction is implemented. c) BicOverlapper parallel coordinates. Gene profiles in the bicluster are highlighted in red. The rest of gene profiles are still visible as a light gray background. Coordinate axes corresponding to conditions in the bicluster are rearranged on the left, and gene profile segments for conditions in the bicluster are highlighted in bright red. Interaction with the parallel coordinates, allowing threshold setting and rearrangement of axes is implemented.
