Hello,<br><br>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. <br>
<br>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. <br>
<br>Do you know why this happens and/or how we could fix it?<br><br>Thanks in advance for any help!<br>Jason<br>
