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

{{{#!python
a = EMData()
b = a.read_images("bdb:refine_00#projections_00")
euler_display(b)

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

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)

Inspecting EMData lists With 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)

Figure Label

Description

A

Symmetrized orientation distribution. Cylinder heights are proportional to the "ptcl_repr" header attribute. You can choose which header attribute scales the cylinder height in the inspector (bottom of C

B

The image corresponding to the selected (yellow) cylinder.

C

The inspector. Note you can change uniformly enlarge the displayed cylinders using the "Point Height" and "Point Width" sliders

Mouse Handling

Mouse Action

Result

Shift + right click

Select a cylinder in A, resulting in update of the image in B
