"""
Generator for masking and thresholding each IC spatial map.
Parameters
----------
comps_img: img-like
The 'raw' ICC maps image.
mask: img-like
If not None. Will apply this masks in the end of the process.
thr: float
The threshold value.
zscore: bool
If True will calculate the z-score of the ICC before thresholding.
mode: str
Choices: '+' for positive threshold,
'+-' for positive and negative threshold and
'-' for negative threshold.
Returns
-------
icc_filts: list of nibabel.NiftiImage
Thresholded and masked ICCs.
