Hi Jessica - A couple of things to fix. The bvecs file has commas in it. The bvals file, if you view it with the more command on linux, you'll see that instead of line changes it has "^M" in between the values. This can happen if it's saved in a windows text editor. You can open it in a linux text editor and save it again.

Hope this helps!
