Thanks, Anastasia I know that TRACULA use probabilistic tractography but if ROIs are not set how determine the origin and the end of a certain tract? I think that the first we have to determine the origin and the end of the tract, the second it constructs possible pathway not with the deterministic way (only 1 direction / 1 voxel) but with the probabilistic way (considering which direction should be next to). Is this comprehension wrong? Thank you.

Hi Anri - TRACULA does not use deterministic ROIs. It uses a probabilistic model of how likely each tract is to go through or next to each of the labels of the freesurfer subcortical segmentation and cortical parcellation, as a function of position along the trajectory of the tract.

Hi Anastasia,
Thank you! It seems work well!! I have another question. Are ROIs for automatic tractography in TRACULA the same ROIs presented in Wakana et al. 2007?

Hi Anri - The problem is in this line: set cmd = ($cmd --ref $cvstempdir/$cvstemp) It should be changed to this: set cmd = ($cmd --ref$cvstempdir/$cvstemp/mri/norm.mgz)
For this to take effect, you need to run "which trac-all" and makethe change in the trac-all file that the which commands shows you.

I do not know what command line you ran and what your configuration file looks like, so it is very hard for me to suggest solutions. Best, a.y On Fri,27 May 2016, Anri WATANABE wrote:

2016-05-21 6:48 GMT+09:00 Anastasia Yendiki <ayendiki@nmr.mgh.harvard.edu>: Hi Anri - The FA values are extracted in the native space of eachsubject, which is why
those are the only coordinates that you see. If you want to display the results ofyour analysis on an average
path, after running trac-all -stat, you can use the stats/*.path.mean.txt files (see also the lastpart of the TRACULA
tutorial). Best, a.y On Wed, 18 May 2016, Anri WATANABE wrote: Dear experts, I use TRACULA to examine a measure (FA) at each voxel in onepathway.
pathstats.byvoxel.txt files show coordinates in native spaceand after converting
those the new files don't show any coordinates which are in MNI space. Could you tell me how can I know MNI coordinate values? Thank you! Regards, Anri
