prepdwi

BIDS-app for pre-processing DWI (denoise, unring, top-up, eddy, bedpost.. )

Analysis levels:

participant: Runs pre-processing including denoising, unringing, top-up, eddy, DWI-T1w registration, T1w-T1w template (MNI152_1mm and MNI152NLin2009cAsym) registration, and bedpost fitting. Writes intermediate output to work sub-folder, and BIDS derivatives output to prepdwi sub-folder.
group: Generates HTML reports with QC for brain-masking and registration steps (if linear registration fails, re-run with --reg_init_participant flag to initialize with transform from another subject)
participant2: Runs probtrackx network connectivity between all regions in a given atlas labels file. Uses either canned atlases with the --atlas option, where predefined atlases are defined in the cfg folder; or can specify a new atlas with the --atlas_* options

Usage: prepdwi bids_dir output_dir {participant,group,participant2} <optional arguments>

      Choose built-in atlas:
          [--atlas NAME (default: dosenbach)

       Available built-in atlas labels/csv:
          cort_striatum_midbrain	dosenbach  yeo17  yeo17_striatum  yeo7	yeo7_striatum

       Customize atlas labels:
          {--atlas_space NAME (MNI152_1mm or MNI152NLin2009cAsym)
          [--atlas_label_nii NIFTI
