Dear experts,

I am using BrainSuite 15c on windows7 64 bit machine.

It seemts that everything is OK for running BDP and I could visualize tracts between ROIs and compute connectivity. However, after saving all tracts as fibers.dft and runnning tractconnect script on Matlab, result.csv file does not contain numerical value between ROIs. What’s wrong with this?

tractconnect (‘fibers.dft’, ‘–label’, ‘XXXX.svreg.label.nii.gz’, ‘–allROI’, ‘–data’, ‘XXXX.dwi.RAS.correct.MD.T1_coord.nii.gz’, ‘–desc’, ‘brainsuite_labeldescription-92.xml’, ‘–pvc’, ‘XXXX.pvc.frac.nii.gz’);

Note that ROIs were restricted to 92 regions.

Hi Tetsuya

May I ask what’s in the brainsuite_labeldescription-92.xml file?
Is it a modified version of the standard BrainSuite description file

Hi,
Thank you for response.

Yes, this label description file is edited from the original one by excluding the ROIs that are not interested in our research and including only 92 cortical and subcortical ROIs. The file structure is not changed but some rows were deleted.

Regards,

Tetsuya

Hi,

Let me post some additional information on this.
(BrainSuite 15c on windows7 64 bit machine)

Tractconnect.mat computed the results between ROIs whos id was between 611-641.
These ROIs are mostly subcortical structures. For the ROIs whose id is between 100-400,
which are mostly in cortical areas, no tract value is computed.

Best regards,

tetsuya
