There are several threads about this in the archives. You need to look at
the eigenectors in dmri/dtifit_V1.nii.gz and check that they are oriented
in a way that makes sense with the anatomy.

Hi
No I did not. Actually, I'm not sure how to do that. Is there any
information on that somewhere I could look up?

This doesn't look right. Are you certain that your gradient table is
correct? Have you looked at the eigenvectors of the tensor fit to make sure
they're in the right orientation?

I tried changing the threshold but that did not help. I am following
exactly the instructions here
http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TraculaOutputs
(Except I changed the file names
So, the command I used was:
freeview -v

Here is a screenshot attached. Should I also email you my files?

Hi Prerona - As I've mentioned to others, you can ignore the "Degenerate
spline segment" message.
I can't tell what you mean by "only traced a part of the trac". Can you
see
the rest of it when you play with the threshold? Are you reconstructing
only
the ILF? If not, do the other pathways look ok? Can you send a screenshot
of
what you see when you run the "freeview -tv ..." command from the
tutorial?
Thanks,

Hello
I have been running trac-paths, and thought it finishes with a message
saying no errors,
I get an error saying ERROR: Degenerate spline segment in the

Also I looked at the result using this command:

but it had only traced a part of the trac on one side and nothing on
the other side
Can you help me understand what went wrong and how to fix it?

Hello,
thank you for your help with the first steps of running Tracula.
I was trying to run trac-all step 3 (paths), but was getting an
error
with the mergedph1samples file. I saw on the mailbase that you have
suggested to run bedpost directly to fix this
I have 3 questions about this:
1) do I need to delete any of the (temporary?) files or folders
created by trac-all step 2 before running bedpost
2) should I run bedpost INSTEAD of trac-all step 2 for the remaining
subjects?
3) you have suggested on the list to run bedpost as:
bedpostx /usr/local/freesurfer/subjects/C001/dmri
is this the same dmri folder as created by tracula step 1 (for each
subject)
Thank you so much for your help with this - I really appreciate it

ERRORS

Hello
I think I spoke to soon!
It ended with errors again.
I get the error message: "bvecs and bvals don't have the
same
number
of
entries"
I saw on some older messages on the mail-base you said
that
we
need
to
check that the number of entries in the bvals is same as
and
bvecs
is
3 times as much as the number of volumes. I have checked
that
this
is
the case
I am wondering if it is some formatting problem? there are
no
spaces
at the end of the file. and there are no end of line
markers
either.
Please could you advise me? I have attached the files and
also
pasted
the contents below
My config file is still the same (as pasted below) except
I
tried
changing
nb0 to 2
(# Number of low-b images
# Must be specified if inputs are not DICOM
# Default: Read from DICOM header
#
set nb0 = 2)
