Dear Anastasia,

I tried the command you suggested me and i obtained the output I attach to the mail.

I would like to ask you if I understood well shot it means. In this case left uncinatus connects the following cortex areas:

ctx-lh-fusiform  
ctx-lh-inferiortemporal 
ctx-lh-lateralorbitofrontal
ctx-lh-medialorbitofrontal
ctx-lh-middletemporal
ctx-lh-rostralanteriorcingulate
ctx-lh-superiortemporal 
ctx-lh-temporalpole  
ctx-lh-insula  

and for each area I have the volume of the path. Is it correct? 

Thanks
Lucia

Hi Lucia - You can probably do that with mri_segstats. Try something like:

mri_segstats --seg dlabel/diff/aparc+aseg.bbr.nii.gz --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt --excludeid 0 --sum output.txt --i dpath/lh.unc_AS_avg32_mni_flt/path.pd.nii.gz

And similarly for any other pathway. See the mri_segstats help for more usage info. Let me know if this gives you what you need.

Thanks Anastasia, this is useful for visualization. But to construct a table
with for each tracts the parcellation regions that it connects do I need to
look at the image?

     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,

           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

                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,

                      should indicate the number of sample
