[Neuroimaging] Wrong fMRI sig.nii shape when loading with nibabel

[Noam Peled]

Hello all,
I'm having an issue with loading fMRI sig.nii files.
I've created two overlays using selxavg3-sess, where the only difference
between them is the surface parameter in preproc-sess and mkanalysis-sess.
In the first I used fsaverage, and in the second the actual subject.
Both seems to be ok via fmri_info and tksurfer-sess.
The problem is when I'm trying to use nibabel to load them.
The fsaverage is getting loaded just fine, whether the other one gets a
(-1, 1, 1, 1) shape.
Here are the file:
sig_fsaverage.nii.gz
<https://www.dropbox.com/s/9ojymqrdd51cslh/sig_fsaverage.nii.gz?dl=0>
sig_subject.nii.gz
<https://www.dropbox.com/s/czysnf8jfsmz753/sig_subject.nii.gz?dl=0>
Any ideas?

Thanks!
Noam Peled
