[scipion-users] Is it possible to calculate the FSC of a 2D class?

[Carlos O. S. <co...@cn...>]

This is a common question. In CL2D, and in principle all other 2D 
classifiers, you may see the average, standard deviation and FSC of any 
class. For doing so,

1) open the images behind the class you are interested in

2) make sure that the geometry is applied (Display -> Apply Geometry)

3) Calculate the avg or FSC (Tools -> ...)

The FSC is shown in digital frequency. The sampling rate in this example 
was 2.12A/pix and the FSC drops below 0.5 at about w=0.075. Then, the 
continuous resolution associated to this class is 2.12/0.075=28A.

See attachment.

Kind regards, Carlos Oscar
