Adding laussane 2008 parcellation to mrtrix software

[milad7093]

Dear experts

I am trying to add the laussane atlas to the mrtrix software and using easy_laussane. I usually use the following code to register the atlas to my dwi data and have the following questions

easy_lausanne --subject_id sub-01 --target_volume /media/sn/5EB4CC35B4CC1207/run/previous_run/sub-01/dwi/session1/sub-01_session1_dwi1.nii.gz --target_type diffusion --output_dir /media/sn/5EB4CC35B4CC1207/run/previous_run/sub-01/dwi/session1

1- Before using easy_laussane, Do dwi data need to be preprocessed (denoising, motion and eddy correction)? 2-when the running finish, easy_luassane creates two types of files: ROI_scale125.nii.gz ROIv_scale125.nii.gz

Can you please explain a little bit about them?
