Hi again Anastasia,

I tried also to convert my three row bvecs file in a three column one but I still got the same "bvecs and bvals don't have the same number of entries" error. I then tried also to change the dot to comma as the decimal separator but still nothing

Ciao Anastasia, I checked and I'm using the latest version of Freesurfer, version 5.3.0. It seems like that the command trac-all path while working on the bvecs table and doing the corrections makes some errors and you can see it from the bvecs file I found in the dmri directory which is only 4 rows long.

Hi Francesco - Which version of tracula are you running? To be able to use bvecs files that are in 3 rows instead of 3 columns, you need to make sure that you have the latest update to tracula, see here:
        http://surfer.nmr.mgh.harvard.edu/fswiki/Tracula/#Updates

This option was not available in the previous releases of tracula.

Hope this helps,
a.y

Hi, 
Sorry Anastasia, I'm seeing that my question was not so clear. The files I sent you in
the first mail are the bvecs and bvals saved by trac-all -prep in the dmri directory.
The original files are in attachment in this mail,

      Hi Francesco - The bvecs file that you're attaching has only 3 vectors,
      while the bvals file has 65 b-values. Are these your original files, or the
      ones saved by trac-all in the dmri/ directory?

            Hi everybody,
            I'm trying to run the trac all -prep command but after some
            times I get this
            error "bvecs and bvals don't have the same number of entries".
            I've checked
            my bvals and bvecs, which are in attach, but they seems to be
            formatted in
            the right way. What can I do? Thanks,

            Francesco Baldacchini
