Name

sxplot_projs_distrib - plot distribution of projections

Usage

Usage in command lines

sxplot_projs_distrib projection output_plot

Usage in python programming

plot_projs_distrib(projection, output_plot)

Example

sxplot_projs_distrib.py proj_15.hdf plot_agls.hdf

Input

projection

the input stack of projections, each projection must contain its angles in the parameters xform.projection

Output

output_plot

name of the output plot file

Description

sxplot_projs_distrib will read the angles (phi, theta, psi) for each projection wrote to the header with the parameters xfrom.projection. Each Eulerian angle of projection will be map on a sphere in order to display the projection distribution to a 2D image. All angles that map on the bottom hemisphere are mirrored to map on the top hemisphere.

The origin angles (0 value) on the map: phi origin is the same for the trigonometric circle with a radius = 1 (alpha = 0) ; theta origin is the top of the sphere, so it is the center of the map ; psi origin is irrelevant.
