I’m a developer on the Virtual Brain project (thevirtualbrain.org). In addition to using the regional connectivity matrix, we’d also like to have the track length matrix as well.
Would it be possible to easily export that? With the current version of BrainSuite what it the easiest way to compute it? I saw that we can export the tracks to a file, but I don’t recognize the format.
I found the DFC file format page and finally understood that the dft file is also this format. I’ve written a Python class to read the curves and now I want to double check: are the coordinates of the tracks in the T1 coordinate system? Or, do I have to apply a diffusion to T1 transform?
In case it is useful for others, I post the short dfc reader I wrote here:
