Hi, I have a few questions that I hope someone can outline for me. My goal at the moment is to extract FA values for anatomical regions in the brain within the HCP participants.
I was attempting to closely follow the pipeline outlined in this link (http://polaris.ssc.uwo.ca/mediawiki/index.php/DTI_analysis) with some changes to allow for the use of CUDA. at the current moment I am trying to run bedpostx on a single participant but it is crashing immediately: >bedpostx_gpu Diffusion -n 3 --cnonlinear --rician --model=3 It crashes in both the stripped down version of the command (bedpostx <Directory> and the one that I have tried above. here is the error log: " terminate called after throwing an instance of 'NEWMAT::IndexException' /bin/sh: line 1: 4602 Aborted (core dumped) /usr/local/fsl/bin/xfibres_gpu --data=/home/TLA/Desktop/100307/T1w/Diffusion/data --mask=/home/TLA/Desktop/100307/T1w/Diffusion.bedpostX/nodif_brain_mask -b /home/TLA/Desktop/100307/T1w/Diffusion.bedpostX/bvals -r /home/TLA/Desktop/100307/T1w/Diffusion.bedpostX/bvecs --forcedir --logdir=/home/TLA/Desktop/100307/T1w/Diffusion.bedpostX/diff_parts/data_part_0000 --nf=2 --fudge=1 --bi=1000 --nj=1250 --se=25 --model=1 --cnonlinear /home/TLA/Desktop/100307/T1w/Diffusion 0 1 > /home/TLA/Desktop/100307/T1w/Diffusion.bedpostX/logs/log0000 " I ran my FSL through FEEDS so I don't think it is an issue with my install of FSL or CUDA. I also did a brief check of the FSL and HCP mailing lists, but nothing had turned up. I wanted to see if theres some particularities with the data that are making this hard for me. I would also like some feedback as to the pipeline I am using.
