Hi Marissa - If your bvecs/bvals files are in row format, you need to make sure that you have the most recent update that supports this. It was a feature that was added later on:

Hi freesurfers, I'm having a problem the bvals and bvecs for one of my subject's DTI data. When I try to run the first step of tracula I get this error message: "Error: data and bvals/bvecs do not contain the same number of entries" I have checked, the bvals and bvecs do contain the same amount of entries (42), and they are in the proper format (bvals one line, bvecs three lines). The entries in the bvals/bvecs matches the number of images within the DTI file as well. Looking online, I saw that this was part of the FAQs on tracula. It suggested making sure the locale settings were correct, which it is (en_US.UTF-8). I've run tracula on every other subject and have not run into this problem, but the same subject had an error with multiple frames when we were processing the T2 images. Could this be related? Any idea about what is going on, or how I can fix it? Thanks in advance, Marissa
