[Chimera-users] visualizing density map

[Elaine Meng]

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
