I’d like to analysis diffusion kurtosis imaging through mrtrix3.
According to tensor2metric manual, diffusion kurtosis imaging analysis is avaliable in mrtirx3.
However, when I use command tensor2metric dt.mif -mk mk.mif is not working on my macos.
dt.mif file is calculated from dwi2tensor.
Is there any option should I do?
The input file dt.mif is probably a diffusion tensor. You need to start from the kurtosis tensor instead. You can check the dwi2tensor help page on how to make it.
Thank you for your answer,
dwi2tensor -dki input output
this command is not working.
should I do something more after dwifslpreproc and dwibiascorrect?
The Kurtosis functionality of
tensor2metric is currently only available on the development branch of MRtrix3, see this answer from Ben: Kurtosis - #2 by bjeurissen
You can build it from source as described here: Question about dev branch of MRtrix3
Thank you for your answer!
