Hi Anastasia,
Just to be clear, is this what you mean by a more diffuse volumetric
distribution. Here is a snapshot of the right inferior longitudinal fasiculous.
I am just getting a better sense of what to look for in terms of bad vs. good
tracts.

Hi all,
I was wondering how you go about looking at dtifit_V1 (the primary eigenvector
of the tensors) displayed as lines in freeview?

Hello,
I was looking at a trac-all log file to get my bearings on what is being done
and making sure things were done successfully,
I did not get any errors for this subject but when I was looking at the right

Hi Anastasia,
Thank you so much, this is really helpful.
I have one other question. So, at the bedpost stage, the no_dif_brain mask is
used correct (looking at the fsl webpage), or at this stage the freesurfer
segmentation is used as well?
If in addition to using tracula, lets say if I also
Hi Anastasia,
So probtractx uses the output from the bedpost stage (which I ran in Tracula).
I noticed that the bedpost stage (in the dmri.bedpostx folder) also outputs a
no_dif_brain mask. I guess what I am worried about is that if bedpost creates
this no_dif_brain mask, that is what will be
Hello,
I have a few questions about Tracula. I am very new to DTI, so I hope you can
bare with me.
1.) I have been checking my registration at the prep stage. I am very new to
this so it may be that I am not looking at the right files.
I looked at my eddy current corrected diffusion data
Hello,
I was wondering if it is better to keep the FA results from a DTI analysis in
diffusion space for group analysis or if you should warp them into standard
space as you would typically do with functional MRI data.

Hi Anastasia,
On a related note, with tracula, you can't let's say track the amygdala to the
vmpfc (there is a study already demostrating that there is a white matter tract
that connects these two structures). Can I do something like that...take
the amygdala as the seed and the vmpfc as
Hi Anastasia,
Although the website says: In addition to the tract-based analysis that can be
performed on the tract-based averages of anisotropy and diffusivity, the same
maps could also be used for other voxel-based and ROI-based group analyses.
So this makes me think that this type of group

I recently modified my script so that it would work on a cluster. I had been

I plan on running a batch of subjects (around 80) on a computer cluster.
I am assuming that in the dmrirc configuration file, I can enter all of the

However, do I have to add something to it to make sure that each subject gets

Hi Anastasia,
We use SLURM.
I have not personally yet run bedpost off of the cluster, but one of my
colleagues was able to run his data off of our cluster ( the whole pathway
including bedpost) without any problem. However he (Jon Wieser) made an
individual dmrirc configuration file script
Hi Douglas,
Thanks for the reply. I am very new to Freesurfer and am more used to scripting
with AFNI.
Would you mind giving me a bit of sample code to get used to what this may look
like? Can I script this in a .tcsh file?
Also, once I convert the aseg to MNI space, can I simply average or

I plan on using the aseg.nii to create a grey matter mask. I want to warp

The reason I need this in MNI space is because I plan to make a group grey
Hello,
I had some questions about setting the dmrirc file for batch processing for DTI.
I set the subject list I put in the 6 subjects I wanted to process. Then in the
dcmlist I put in the pathway to the data files for each subject. I put a space
in between each subjects pathways. Then I put

I am running into the following error when I try to run trac-all:

Hello Anastasia,
Is it okay to run my DTI data on Freesurfer 5.3 when all my recon-all scripts
for the structural data were run in Freesurfer 5.0?
And I can download the tracula program straight from the tracula Wiki? And it
will work for Linux?
Thanks so much!
