KB005501: To save the clustering picture with only the full tree excluding the big tree on the left side. 

To save the entire cluster tree outside GeneSpring GX10, you could right click on the image and select Export As -> HTML or as Image. HTML would allow you to export the entire image.If you choose 'Image' option to export, then please uncheck the option "Export only the visible region". Also you could change the units from inch to cm and set the required range.
