Hi, I am trying to compare two cryoEM density maps of the same protein, the only difference between them is a conformational change. Is there a way to switch directly from one volume to the other without having to display both of them together in between?

Hi Montserrat, The new morph map tool can switch between two maps without displaying both. You might be interested in showing interpolated maps as well which that tool does. You can obtain it from the Chimera experimental features page. http://www.cgl.ucsf.edu/chimera/experimental/experimental.html There are instructions on how to install it with your current Chimera (1.2304 or newer). It is presently not included in the Chimera distribution. Here's documentation for it. http://www.cgl.ucsf.edu/chimera/experimental/morph_map/morphmap.html If you just want to switch between the two maps without interpolation use morph map step of 1. If this is an inconvenient way to do the simple switching you want I could add a keyboard shortcut that hides the current map and displays the next one. Tom

Hi Montserrat, I forgot to mention that there is a new Chimera tutorial with a section on using the morph map tool. http://www.cgl.ucsf.edu/chimera/tutorials/eman07/chimera-eman-2007.html Tom
