Hello,
I'm trying to run eddy_cuda 8.0 on some older DTI scans using fieldmaps that were not generated by topup (they are the standard Seimens stock scans-2 magnitude, 1 phase). I am also submitting this to our remote cluster via slurm. I have run the eddy_cuda8.0 command on all subjects without the --field option and it ran fine on everyone. When I use the --field option I get the following error for some subjects:
CUDA error after call to EddyKernels::spline_interpolate
Error message: an illegal memory access was encountered
Do I just need to request more memory when I submit my job to our cluster or is this a different issue? I've posted the eddy command below for completeness:
eddy_cuda8.0 --imain=../dti/${SUBJ}_dti --mask=../dti/${SUBJ}_dti_brain_mask --field=${SUBJ}_fieldmap_flirted_HZ --acqp=../../../scripts/acqparams.txt --index=../../../scripts/index.txt --bvecs=../dti/${SUBJ}.bvec --bvals=../dti/${SUBJ}.bval --repol --out=${SUBJ}_eddy_corr --mporder=6 --slspec=../../../scripts/slspec.txt --s2v_niter=5 --s2v_lambda=1 --s2v_interp=trilinear
Thanks!
Amanda
