Hi Anastasia, Each diffusion volume has 128x128x60 voxels, and there are 182138 voxels inside of the brain mask.

Hi Rui - How many voxels are in your diffusion volume? How many of them are inside the mask?

Hi all,
I'm running tracula and when doing the step: trac-all -prior -c single_subject
After some time it gives this error:
MRIalloc(218, 182, 182): could not allocate 158704 bytes for 49th slice
Cannot allocate memory
I' m running tracula on Ubuntu 10.04, with 4GB ram. The diffusion data is DTI with 64 directions.
This happens many times? I need more memory?
Best regards,
