Hi Jesus, There is a tricky way to do a projection of a map in Chimera. You can use the map binning capability. For example, if map #0 has 144 planes along the z axis I can add all those planes with vop bin #0 binsize 1,1,144 This can be done with a dialog instead of a command using Tools / Volume Data / Volume Filter, filter type bin and type in the bin size as 1 1 144. You also want a view along an axis other than x, y or z it sounds like. To do that you would resample the map on a new rotated grid so that the z axis is along the desired projection axis. The following video shows how to use the Chimera volume dialog subregion selection capability to do that http://www.cgl.ucsf.edu/chimera/videodoc/rotatedbox/ Tom -------- Original Message -------- Subject: Re: [chimera-dev] 2-D projection of volume in Chimera From: Elaine Meng To: Jesus Montoya Date: 3/4/13 11:59 AM
Hi Jesus, Sorry, I don't think there is a way, currently. Here is the most recent information I could find on that topic:

Hi,
Is there a way to project a 3-D volume into a single 2-D image plane in Chimera?
For example, I want to load a volume twice into Chimera and view the two copies side by side in an identical orientation (manually set by rotating the volumes with the mouse). Then, I want to view one of them as a 2-D projection along the axis that comes out of the screen.
While a "solid" representation of the volume is similar, it is not exactly what I need...
Thanks!
