Diffusion Kurtosis Imaging analysis

Development
1

Hi, experts.

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?

Hi,
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.
Kind regards

Thank you for your answer,

However

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
