Hi Kristian, split_parts_gpu was included in FSL 5.0.9. It should be in your ${FSLDIR}/bin directory. Are you using this version of FSL? If for any reason is not there, you can download a binary version compiled with CentOS 6.7 from here: http://users.fmrib.ox.ac.uk/~moisesf/bedpostx/split_parts_gpu_CentOS6/split_parts_gpu.zip And copy it to ${FSLDIR}/bin directory. The patch in http://fsl.fmrib.ox.ac.uk/fsldownloads/patches/bedpostx-patch-fsl-5.0.9.tar.gz is for FSL 5.0.9 as well. Did do applied that patch ? You just need to copy all the files to your ${FSLDIR}/bin directory. Moises. On 21 July 2016 at 22:31, Kristian M.
