[Chimera-users] problem with electron density map

When Chimera opens a map larger than a certain size it only shows one plane. Pressing the “All” button below the histogram that appears when a single plane is shown will show all the planes. The size threshold for showing one plane is set using menu Volume Viewer / Features / Data Display Options.

There is an option that, when the data is over a specified size, only shows one plane to start with, but your image looks like more than one plane is shown. To set options related to initial display of large data, use Volume Viewer menu “Features… Data display options”
