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. Emily - Original Message - From:

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

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
