[Mrtrix-discussion] dwi2response

[Robert Smith]

Hi Aaron

The method for estimating the response function in the new MRtrix package
is relatively novel, and although I configured the program as best I could
to work on the data I had on hand to test it with, there are quite a number
of free parameters in the algorithm that are difficult to configure in
order to handle all possible acquisitions.
I'd expect the program to take longer to execute for low b-value data, but
it certainly should not be taking 36 hours.
If possible, I'd appreciate private access to an example problematic data
set so that I can see what's going on and hopefully improve the heuristics
within dwi2response to better handle these data.

Best regards
Rob
