Can someone please advise on the computing power required for the statistical analysis step for fiber density (step 16 in the fixel analysis). I am running an analysis with ~100 subjects and am unable to do so on a 4 core computer with 16GB of memory without crashing the computer. The memory load required for this step seems a bit unreasonable. I’ve even run into memory issues trying to run this on a super computer cluster. I’ve been at the last step of this analysis for over a month now and I guess the next thing to look into is possibly upgrading lab computers. Are people running these analyses on 64GB+ machines and if so what is the expected timeframe of this analysis?
Thank you in advance,
