xcp_d.utils.bids.collect_morphometry_data

xcp_d.utils.bids.collect_morphometry_data(layout, participant_label)[source]

Collect morphometry surface files from preprocessed derivatives.

This function will look for fsLR-space, 91k-resolution morphometry CIFTI files.

Parameters:

  • layout (bids.layout.BIDSLayout) – BIDSLayout indexing the ingested (e.g., fMRIPrep-format) derivatives.

  • participant_label (str) – Subject ID.

Returns:

  • morph_file_types (list of str) – List of surface morphometry file types (e.g., cortical thickness) already in fsLR space. These files will be (1) parcellated and (2) passed along, without modification, to the XCP-D derivatives.

  • morphometry_files (dict) – Dictionary of surface file identifiers and their paths. If the surface files weren’t found, then the paths will be Nones.
