EMAN2's EulerXplor Tool

The four interfaces in e2eulerxplor. See the table below for more details

Figure Label	Description
A	This is a graphical depiction of orientations on the asymmetric unit. Click on one of the dots to display the associated class average and projection as shown in C. The color of the dot in the asymmetric unit shows the relative number of particles in the class: Blue indicates a class with a lot of particles in it, red indicates a class with few particles in it. White is in between.
B	This is main inspector, this appears when you middle click on A. You can select different refinement iterations to investigate how the class averages and aligned particles are changing through time.
C	Projection (left) and class average corresponding to selected orientation (yellow) in A
D	Aligned particles that formed the class average shown in C (right). If you select the projection in C (left) these particles will be shown unaligned. Blue squares indicate that the particle did not make it into the final class average

euler_display from e2.py

You can open a list of EMData's with the EulerXplor tool if they all have the "xform.projection" header attribute. Use this syntax:

   1 a = EMData()
   2 b = a.read_images("bdb:refine_00#projections_00")
   3 euler_display(b)

Similarly you can look at a list of Transforms with the EulerXplor tool, using this syntax:

   1 sym = Symmetries.get("c1")
   2 orients = sym.gen_orientations("eman",{"delta":3,"inc_mirror":True})
   3 euler_display(orients)
