[Pytom-mail] CPCA with binning

[Dustin M. <dus...@gm...>]

Hi all,

I get an error with calculate_correlation_matrix.py when I try to use binning.

Traceback (most recent call last):
  File "/share/apps/pytom/classification/calculate_correlation_matrix.py", line 246, in <module>
    worker.start(job, verbose)
  File "/share/apps/pytom/classification/calculate_correlation_matrix.py", line 54, in start
    self.run(verbose)
  File "/share/apps/pytom/classification/calculate_correlation_matrix.py", line 110, in run
    vf = f.getTransformedVolume(binning)
  File "/share/apps/pytom/basic/structures.py", line 1863, in getTransformedVolume
    volumeTransformed = vol(volume.sizeX(),volume.sizeY(),volume.sizeZ())
AttributeError: tuple object has no attribute sizeX

I traced the error to pytom.basic.structure.Particle.getVolume and at line 1631 the call to resize
actually returns a tuple of the resized volume and the Fourier volume. This patch seems to fix things.

1631c1631
<                 volume, fvolume = resize(volume=volume, factor=1./binning, interpolation='Fourier')
---
>                 volume = resize(volume=volume, factor=1./binning, interpolation='Fourier')

Hope this helps anyone who runs into the same problem.
