[Neuroimaging] Use of atlas to compute Z-Scores

[Gabriel Reynés]

Dear Christophe  ,


Thanks for your answer! I spent many hours triyng to figure the behaviour
of NiftiLabelsMasker
I do not understand how to iterate over each mask ROI.

How one can iterate over each label of a masker?

`# Obtain AAL Atlas
aal = datasets.fetch_atlas_aal('SPM12')
aal_labels = aal.labels

# Obtain mask
masker = input_data.NiftiLabelsMasker(aal.maps)

# Input image to compute the mean value for each
patient_img = image.load_img(path_nii)
patient_img  = patient_img.get_data()

# Fit the mask to the image
masker_fit(patient_img)
mask_img = masker_fit.mask_img_

Thanks in advance,


Gabriel
