Hi Gerit - The bvecs file that's fed into dtifit has commas instead of dots as the decimal mark. I'd try "setenv LANG en_US.UTF-8" in your unix environment and rerun to see if that fixes the problem.

Hope this helps, a.y

Dear all,

despite reading the list and having tried various versions of the bvals and bvecs files, I still get the message in dtifit:

Error: bvecs and bvals don't have the same number of entries.

but it also says "trac-preproc finished without error" and the generated bvals and bvecs in folder dmri look similar to the ones from the tutorial (tab stop checked, everything done in Ubuntu, no OS Windows anywhere)

but when I then try to run trac-all -bedp -c owndata the process finished after 1 min with 0 slices processes.

I attach the bval and bvec files as they are from the scanner, as they are modified by me according to the tutorial instructions (1 column and 3 columns) and how they look after the cp command in the folder dmri (there is no error message during this step) Attached also the log file (error message on line 357).
