[Mrtrix-discussion] Track weighted imaging

[arswitze at ucalgary.ca]

Hello Romain,

   Thank you for your reply. Which option within in tckmap would I use to
create a density volume that weights the tracks by a functional
connectivity value? In other words, is there an option that could
combine the tractogram with a functional connectivity map (transformed
into diffusion space) where the sum of the functional connectivity
values along a track would be calculated, and that sum would be
assigned to the entire track. The final map would have a track weighted
image that is weighted by the associated functional connectivity
values. This method was outlined in this paper:
http://www.sciencedirect.com/science/article/pii/S1053811912012402 but
I have been unable to recreate it.

Thank you for your help,
Aaron
