Module Overview
Purpose of this Module
The bulk of the information required to process the ASL data is stored within the separate BIDS sidecars by the end of the BIDS Import module.
However, there are still some "global" parameters that need to be defined in order for ExploreASL to know how to process the data. These parameters address concepts such as:
- Which subjects should be processed at runtime? Which shouldn't?
- What modeling assumptions should be made for the ASL data?
- Do we want to prioritize quality over speed when processing?
- Should DARTEL be used to create between-subject registration templates?
- Should motion correction be performed on the ASL data? If so, what T-value threshold should be used to determine which volumes should be discarded?
- Which atlases should be used to parcellate region-of-interest CBF data?
These parameters are stored in a file called DataPar.json which, when created through this module, will be stored under the study root directory.
For a more in-depth explanation of the parameters stored in DataPar.json, please refer to the ExploreASL backend's documentation website.
Sections of this Module
This module is broken down into the following sections:
Each section is available either through the navigation menu of ExploreASL-GUI or through the tabs located at the top of the module once you have navigated to it.
