[Chimera-users] How to open four volumes simultaneously in Chimera

[Elaine Meng]

Hi Barnali,
The >3 data sets are all still open.  It is just that the Volume Viewer dialog only shows 3 histograms at a time by default.  You can increase that number using the Volume Viewer dialog menu: "Features… Data display options” and then adjusting the "Maximum number of histograms shown”.

Even if you don’t show all the histograms at once, you can still access each data set from the Volume Viewer menu: Data…

I hope this helps,
Barnali
