Hi Sandra - Bedpost is an FSL program, so your question would be best

Nope, sorry about that. The reason for keeping them separate is that the
middle step is running bedpostx. It's the lengthiest step and we typically
run it on a cluster. When run on a cluster it's parallelized by slice, and
the other 2 steps are parallelized by subject. One could try to queue up

Hi Viviana - If you upload this data set I'm happy to look at it.
Also, I strongly recommend getting the updated version of trac-all from
the wiki (I'm guessing from the log file that you're probably not using
that?) See 2012/01/09 update here:

Ciao Sarina - The problem is here "fslorient: Command not found." You have
to make sure that FSL is properly installed and the FSL executables are in
your path, as trac-all calls a few of them.
Hope this helps,

Hi Fabricio - You can only use the formats supported by mri_convert:

Dicom or nifti is recommended.

Hi Richard - I'd check your bedpostx output files, run mri_info on them to
make sure they have the right number of slices. The monitoring script that
produces the "slices processed" messages checks only every once in a
while, so you won't see a separate message for each slice.

Hi Andi - I'm pretty sure we were already planning to change some of the
mutualinfo's to corratio's in the next release, so no, this is in no way
an official endorsement!

Hi Carolina - Tracula is not an exploratory method for tractography from
any seed region of your choice. It reconstructs a specific set of 18

Hi Gabor - The input DWIs can be in any format that can be read by
mri_convert, including the NIfTI format. The gradient directions should be
in voxel coordinates, like the ones used by FSL. I don't have experience
with dcm2nii, but if you have original DICOM files, you can pass those as

the standard DTI accurate and TRACULA able to extract the bvals and bvecs
from the dicom files?

Hi Kiely - Looks like you used flirt for the intra-subject registration,
so you can look in trac-all.log for the flirt command line that registers
diffusion to anatomical and play around with the parameters.
You can also use bbregister instead of flirt for the intra-subject
registration - it
No, this is something you have to try yourself on the command line. If you
want to make the change permanent, you can edit the relevant line in
$FREESURFER_HOME/bin/trac-preproc.
