I think I found the problem. I reduced the number of train files in the trainlist.txt file and it ran without errors. Maybe I will need more memory to run with all train files.

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,
