Dear All,

I’m trying to load a pretty big diffusion MRI dataset (320x320x260x122).

I’m running matlab 2015a 64bit on a linux machine.

I’m using MRIread, which in turn calls load_nifti.

I’m getting the following error:

Error using  +

Out of memory. Type HELP MEMORY for your options.

Error in load_nifti (line 158)

  hdr.vol = hdr.vol * hdr.scl_slope  + hdr.scl_inter;

Error in MRIread (line 158)

hdr = load_nifti(fspec,headeronly);

When I load half dataset (320x320x260x61) it works ok.

I tried to increase the Maximum array size in Matalb (default 1,000 - now 10,000), but I’m still getting the error.

I tried to change machine (which runs matlab 2013a on linux) and it worked fine.

I think this is due to some matlab settings.

Can anyone help?

Thanks a lot,

Ilaria
