Hi there,

I have a question regarding the tck2connectome command. I would like to build a *n x p* connectivity matrix where *n* is each seed voxel (in a seed mask) and *p* is each ROI used for tractography.

It seems that the default option is to have a node-node connectivity matrix (where half of the values would be repeated or it would be an upper triangular matrix).

Is there a way to create the matrix by generating a vector of streamlines for each seed voxel to the ROIs, and concatenating them?

Thanks so much!
