PS. I run my own data and got bfc.nii.gz, but how to get .dwi.bval and .dwi.bvec and dwi.nii.gz file to fun BDP?
Bvalue (.bval) and Bvector (.bvec) files are sampling protocol information of your dwi file. This should be provided as input to run BDP – It should have been published along with your diffusion data.
