[Mristudio-users] Fiber Tracking Saving Data Question

[Jason Stein]

Hello,

I ran some fibertracking on a DTI set and am trying to get the corticospinal
tract.  As per "Automated Fibertracking of Human Brain White Matter Using
Diffusion Tensor Imaging", I placed seeds as follows, an cerebral peduncle
AND motor cortex NOT contralateral hemisphere NOT cerebellum.  After that I
got a bundle which corresponds very well to the corticospinal tract.

Now, I saved this dataset in both the Amira's format and the .dat format.
When I reload the dataset into DTIstudio or using other code, it shows up in
the wrong place (a few voxels off from where it originally started).  I
attached a screenshot of this problem where you can see that in
OriginalFiberTract.jpg, the tract originates in the cerebral peduncle and in
the ReloadedFiberTract.jpg, the tract originates in a place slightly
posterior to the peduncle.

Do you know why this happens and/or how we could fix it?

Thanks in advance for any help!
Jason
