Hi Anastasia, I apologize but I do not find CVS template? Where it should be located? Thank you very much,
Stefano

Hi Stefano - Did you try CVS for the inter-subject registration? It doesn't look like it from the configuration file.

What registration methods are you using for the intra-subject and inter-subject registration? Have you tried the different options?

Yes, 5.2. Incomplete tracts are usually fmajor or cab. Rarely fminor.

What you say "again" you mean with 5.2?

Hi Anastasia, yes, for some subject the low-b volume is in the end. Some subjects have again incomplete tracts. I'm attacking an example of configuration file that I'm using. I hope that you can check it please.

Hi Stefano - In your case we determined that the ones that had the low-b volume in the end didn't run correctly, right? In that case, I didn't
need
to see anything, you were going to try running 5.2.

Hi Anastasia, could I send you the data of a subject that I don't run correctly?
I still have some subjects with tracts incomplete and I do not know if
it depends
from
my analysis or whether the images are not good.
Thanks,
Stefano

Hi Gerit - If it's not an issue with the gradient table but instead a tractography initialization issue, I strongly recommend running 5.2
with
bbregister for the registration (which is the default in 5.2 anyway).
You can also upload an example data set with issues (include: dmri, dmri.bedpostX, dlabel, dpath, scripts) here for me to take a look: https://gate.nmr.mgh.harvard.edu/filedrop2/
Hope this helps, a.y

Dear Anastasia,
thanks for the help. There is also a line option in freeview.
However
we still
have
brains with missing tracks, I rerun them with increasing the ncpts
and
registering
to
bbr (since that is default in Tracula 5.2.). We are reasonable
confident that our
bvel
and bvac are correct, since we have roughly 20 cases out of 90
processed brains
where
there are no missing tracts. Further sometimes only one tract is
missing,
sometimes
it
is more severe. We could not find any correlation with recon-all
problems or DTI
raw
data issues (all but one were without moving artefacts). Since we
are
running
bedpostx
outside of trac-all (i.e. trac-prep then bedpostx then trac-path)
might it be an
issue
that is solved with installing the 5.2. version? Would that run in
freesurfer
5.1.0?
I guess we need to change the dcmrirc files only a bit.
Kind regards Gerit Pfuhl
