Always calculate parametric images before spatial normalization

For example, in branch # 5 the PET image is first spatially normalised, and only after that are the parametric images calculated. Reversing the order would

  1. Provide native space parametric images
  2. Speed up the process because in native space there are fewer voxels in which the modelling needs to be done

This is more complicated than expected: When MRIs are not used in the processing, then the brainmask is in the MNI space. This change may still be useful, but it requires coming up with a new way to produce the brainmask without MRI. Perhaps in these cases the brainmask should be based on the meanpet image?

Parametric images are now always calculated before spatial normalization.

Just curious how can I find the images in the output folder. I only saw the ones after normalization.
