There are different conventions for the definition of Euler angles. This is one reason we try not to use Euler angles in Chimera. Perhaps Spider uses a different convention. Here's Chimera's convention. http://www.cgl.ucsf.edu/chimera/current/docs/ContributedSoftware/transform/t... Tom
Hi again,
I am having trouble trying to orient my map using the tools / movements / transform coordinates. My euler angles are an SPIDER output, but when I type them in Chimera they do not match my spider projections, any solution?
Thanks in advance,
Alex.

Hi Alex,
The ability to position maps using Euler angles was just added so you have to get a Chimera "daily build" from the download page to use it. The menu entry will be
Tools / Movements / Transform Coordinates
without the word Molecule if you are using a recent daily build.

Dear all,
I would like to change the coordinates (Euler angles) for an EM density map (Tools --> Movements --> Transform molecule coordinates). But in the molecule scroll menu, my map does not appear. Is possible to define the system coordiantes for a EM density map?
Thanks in advance,
Alex.
