Hi Laura - Were these bval/bvec files created on windows or with excel by any chance? When you view them in unix (with the more command for example) you'll see an "^M" character instead of every end-of-line. Can you try editing these files in a unix editor to fix that? Let me know if this solves the problem.

Hi Anastasia, Thanks so much for your help! Attached are bvec, bval and trac-all.log files. I have been stuck at one of the preprocessing steps (trac all) for some time and keep getting the error: bvecs and bvals don't have the same number of entries. I saw a couple blogs online about this, but did not see any resolution. I am wondering if it is because the B0 images are interspersed? (see attached bvec file). If you have any insight, I would love some feedback whenever you get the chance. Laura
