aslprep.workflows.base module

ASLprep base processing workflows.

init_aslprep_wf()

init_single_subject_wf(subject_id)

Organize the preprocessing pipeline for a single subject.

It collects and reports information about the subject, and prepares sub-workflows to perform anatomical and functional preprocessing. Anatomical preprocessing is performed in a single workflow, regardless of the number of sessions. Functional preprocessing is performed using a separate workflow for each individual ASL series.
