Hello Tom, Thanks for the answer... It is a nice alternative. Although, it's kind of more difficult to manually translate a precise amount of nm. Is there a way, like with the "plane" option, to control precisely the width and the translation of the subregion box? Maybe through a command line, but I have found it...

The "planes" panel can only display slices perpendicular to the volume axes as you found. There's a video showing how to show the oblique slice on the Chimera video tutorial web page http://www.cgl.ucsf.edu/chimera/videodoc/slice/index.html The Chimera volume guide has a text description of the procedure. http://www.cgl.ucsf.edu/chimera/data/tutorials/volumetour/volumetour.html#re... Tom Hi, I'm using the "Feature >> Plane" options of the "Volume viewer tool" to show contour lines in planes of density maps. For the plane, there are 3 options: "X-axis", "Y-axis", and "Z-axis". The plane I'm interested in is none of those. I try to rotate the maps, but the X, Y and Z axis are also rotating... Do you know if there's a way to rotate the "axis" and the "map" independently, please? Thanks in advance, Nicolas
