Hi, I still have difficulties to understand how goCluster works. To display one of the identified GO terms i have switched the visualization method to heatmap. But i don't know for which go terms (the selection attribute) it is going to work, for some it is ok but for others it doesn't. Can someone help me ? Thanks for your help TM -- MOUROT Tabar?
