Why can't I segment my T1w data?

import ants
import numpy as np
in_brain = '/Users/derekpisner/Downloads/tuning_derivatives/BIDS/sub-25637/ses-1/anat/

sub-25637_desc-preproc_T1w.nii.gz'

img = ants.image_read(in_brain)
mask = ants.get_mask(img)

In [30]: img

Is this because it’s 3d?

Here’s the file: https://drive.google.com/file/d/1OuDofzvWa8ZtSnB0xseO0EezTWhwgsul/view?usp=sharing @dPys

It’s probably because you have a spacing of 0 in two of three dimensions.

@stnava – that worked. Thanks to both of you! Will close now and if I experience any further issues, I’ll reopen a new issue.
