clinicadl.io.bids.DwiDti¶

class clinicadl.io.bids.DwiDti(measure: str | DTIMeasure, space: str | DTISpace)[source]¶

BidsFileType to select Diffusion-Weighted MRI (DWI) images preprocessed with Clinica dwi-dti pipeline.

Parameters:

measure (str | DTIMeasure) – The DTI-based measure to use, among FA (fractional anisotropy), MD (mean diffusivity), AD (axial diffusivity) and RD (radial diffusivity).
space (str | DTISpace) –
Either native (the data in the native space) or normalized (the data in MNI152Lin standard space):
- with native: only the files that match the pattern dwi/dti_based_processing/native_space/sub-*_ses-*_space-{b0|T1w}_{measure}.nii* will be selected.
- with normalized: only the files that match the pattern dwi/dti_based_processing/normalized_space/sub-*_ses-*_space-MNI152Lin_res-1x1x1_{measure}.nii* will be selected.
