[Numpy-discussion] Loading large NIfTI file -> MemoryError

Hello together,

I try to load a (large)  NIfTI file (DMRI from Human Connectome Project,
about 1 GB) with NiBabel.

import nibabel as nib
img = nib.load("dmri.nii.gz")
data = img.get_data()

The program crashes during "img.get_data()" with an "MemoryError" (having 4
GB of RAM in my machine).

Any suggestions?

Best regards,
