Hi Lucia - You can look at the tracula output over the cortical parcellation and subcortical segmentation in the individual's diffusion space like this:

freeview dmri/dtifit_FA.nii.gz dlabel/diff/aparc+aseg.bbr.nii.gz:colormap=lut:opacity=.5 -tv dpath/merged_avg33_mni_bbr.mgz

Hope this helps,
a.y

Dear Anastasia and all,

how can I understand which are the region of the brain in which the brain

base been parecellated that each tract generated by TRACULA connect?

For example  if I look at the left uncinate fascicles how can I know which

are the ROIs of the statistical output from the cortical parcellation that

it connects?

Thanks

Lucia

     Hi Anastasia,

thanks for you answer. Now I have understood the meaning of that

parameter.

Best regards

     Hi Lucia - It's how many sample paths were drawn to

     produce the probability distribution of the path

     (path.pd.nii.gz). It depends on the configuration

     parameters (nsample, nkeep), so it'll be the same if these

     configuration parameters are the same.

     Hope this helps,

           Dear all,

           I noticed that in the TRACULA statistics

           output files (pathstats.overall.txt) the

           variable "Count" that

           should indicate the number of sample paths in

           the WM tract is the same for all the computed

           tract. Could

           anyone tell me why this happen?

           Thanks a lot

           Regards
