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
