Dear Peter,
Thank you very much for your kind and detailed explanation.
Please forgive me about the following q:
my fiber's data (fibers.mat) is represented as a structural object in
Matlab.
Does Mitk enable to import such a Matlab's data?
Anyway, how my program can read the data from that fiber.mat file?
Thanks in advance.
