Thanks! What do you mean by my "original TLR108.bvec file"? I think the issue may be that the bvec and bval files were originally created using dcm2nii before we had decided to use Tracula. I am just having trouble determining in which directory the original bvec and bval files were created, because it seems like those are outdated and incorrect and are affecting the creation of bvecs and bvals in the dmri directory
Sorry for my naïve questions- I really appreciate your help.
