Hi Francesco, There is a setting that initially shows just one plane if the data is bigger than a certain size. Maybe that is what happened. If so, you can show the whole thickness of the data by: (1) in the Volume Viewer menu, checking Features... Planes (2) in the Planes section that appears, clicking the "All" button You can change the setting for initial plane display by: (1) in the Volume Viewer menu, checking Features... Data display options (2) in the Data display options section that appears, either turning off the option "Show plane when data larger than N Mvoxels" or leaving it on but changing the Mvoxel size limit that triggers such display (3) in the Volume Viewer menu, choosing Features... Save default dialog settings I hope this helps, Elaine ----- Elaine C.
