Hi Daan, Antonin,
As Antonin mentioned, nthreads = 0 in linux doesn’t solve the problem. I run the same command, on mac nthreads by its default value, and in Ubuntu using - nthreads 0.
Mac:
tckglobal 19_5_biascor.mif 19_5_wm.txt -riso 19_5_csf.txt -grad grad_rot.txt -mask 19_5_biascor_mask.mif -length 0.6 -niter 1e9 19_5_globaltracks.tck -force
Ubuntu:
tckglobal 19_5_biascor.mif 19_5_wm.txt -riso 19_5_csf.txt -grad grad_rot.txt -mask 19_5_biascor_mask.mif -length 0.6 -nthreads 0 -niter 1e9 19_5_globaltracks.tck -force
