aslprep.sdcflows.workflows package

Fieldmap estimation and unwarping workflows.

Automatic selection of the appropriate susceptibility-distortion correction (SDC) method

If the dataset metadata indicate that more than one field map acquisition is IntendedFor (see the BIDS Specification), the following priority will be used:

1. PEPOLAR techniques (or blip-up/blip-down)

2. Direct B0 mapping sequences

3. Phase-difference B0 estimation

4. Fieldmap-less estimation (experimental)

Table of behavior (fieldmap use-cases):

Fieldmaps found	use_syn	force_syn	Action
True		True	Fieldmaps + SyN
True		False	Fieldmaps
False		True	SyN
False	True	False	SyN
False	False	False	HMC only
