Hello,
I have dMRI resolve dataset of 26 subjects. The dataset resolution is 220x110x15, with 63 diffusion weighted images and 7 b0 images in AP and 5 b0 images in PA phase encoding. Total 12 (7+5) b0 images enters topup. Output of topup enters eddy, also merged AP+PA acquistion images (63+7+5) enters eddy, then bvecs, bvals etc...
For some subject this preprocessing works well (total duration for example 1-2 hours). However for about half of subject it get stuck at eddy. When I turn on diagnostic messages (--verbose) it gets to "evaluating prediction maker model" after 10 minutes of computing and nothing more. The same message is there after 12 hours.
I am now wondering why it get stucked, because for some subjects it is working really well. Could anyone please help me?
Here is the output:
eddy_openmp --imain=eddy_input_resolve.nii.gz --mask=mask_r.nii.gz --index=index.txt --acqp=acq_file_resolve.txt --bvecs=eddy_input_resolve.bvec --bvals=eddy_input_resolve.bval --topup=topup_resolve --out=eddy_resolve -v
