Hi Anastasia, my first idea was also that something else might disturb the process, but i replicated the error several times and observed the memory load in the system monitor without running anything else, seemed not memory-intensive at all.. I use a 10 b0 + 64dir DTI sequence, 2.3×2.3×2.3 mm3, TR=7500 ms, TE=86 ms. The preprocessing, dtifit and bedpostx with FSL worked fine.

What are the dimensions of your DWI series? Were you running anything else at the same time that was memory-intensive? a.y On Thu, 11 Apr 2013, Antonenko, Daria wrote: > Hi Anastasia, > I'm running tracula on linux ubuntu (mint 14) on a lenovo thinkpad edge. it > has 8gb ram and 4 CPUs, i think it's a lot..
