Hi,
I ran probtrackx to obtain seed*seed connectivity matrix.
I used 116 AAL ROI's, so I ran '1 seed*116 target' probtrack 116 times for one subject.
As a output, I got 116 matrix_seeds_to_all target.nii.gz.
I guess first row is for index of voxels in target ROI,, second row for target ROI index(0~115), and third for seed( all 0), and forth row for number of streamlines that connects seed to each indexed voxel of ROI's.
So, I used 'matrix_seeds_to_all_targets' file to generate 116*116 (seed*seed) matrix by summing all streamlines that connects same pair of ROI's.
Did I understand correctly?
Any comment would be appreciated.
