Hi Dear Mrtrix Community.
I am trying to eastimate the DKE/DKI maps estimation using Mrtrix commnad:
dwi2tensor “$dwi_file” “$tensor_output.mif” -mask “$mask_file” -fslgrad “$bvec_file” “$bval_file” -dkt “$dkt_output.mif” -force
as output i get dkt_output.mif, however when i used tensor2metric to get DKE/DKI maps itgive error “[ERROR] unknown option “-rk”” and same for other metrics.
However, at mrtrix documenetation page there is mentioned that you can get Diffusion Kurtosis metrics.
(tensor2metric — MRtrix3 3.0 documentation)
Diffusion Kurtosis Imaging
- -dkt image input diffusion kurtosis tensor.
- -mk image compute the mean kurtosis (MK) of the kurtosis tensor.
- -ak image compute the axial kurtosis (AK) of the kurtosis tensor.
- -rk image compute the radial kurtosis (RK) of the kurtosis tensor.
- -mk_dirs file specify the directions used to numerically calculate mean kurtosis (by default, the built-in 300 direction set is used). These should be supplied as a text file containing [ az el ] pairs for the directions.
- -rk_ndirs integer specify the number of directions used to numerically calculate radial kurtosis (by default, 300 directions are used).
Anyone can help, Please
