Hi, Thanks for your answer. I use ubuntu 12.04 32 bits and python 2.7 I upgrade numpy to 1.8, but the error persists I think that the problem is in gzip.py : max_read_chunk = 10 * 1024 * 1024 # 10Mb What do you think? Best regards, AMIRA 2013/12/31 <numpy-discussion-request@scipy.org>

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, AMIRA
