Hi Matt, Take a look at the _savePosition() routine in chimera/share/Midas/__init__.py that defines the contents of each position: return ( viewer.scaleFactor, viewer.viewSize, cam.center, cam.nearFar, cam.focal, xforms, clips, om.cofrMethod, cofr, viewer.clipping, cam.fieldOfView, ) These are the fields you see in the session file. Notice it has the camera focal plane position (cam.focal) but no eye separation parameter. Tom On Dec 5, 2013, at 5:09 AM, "Dougherty, Matthew T" wrote:

Hi Tom,

I was looking at a typical savepos as it is saved as a session file, below

Can you tell me how to interpret it contents? Trying to understand what parameters are kept.
