MRICloudCalculateDiffmap

Purpose. Build 3D control, label, and difference (control − label) maps by averaging over ASLContext volumes.

Inputs

• If data_descrip["SingleDelay"]: uses derivatives/<sub>/perf/r{asl}.nii

• Else (multi-delay): uses derivatives/<sub>/perf/{asl}.nii

• Requires ASLContext entries ("control" and "label").

Outputs

• r{asl}_ctrl.nii — averaged control image (3D)

• r{asl}_labl.nii — averaged label image (3D)

• r{asl}_diff.nii — difference image (3D)

All saved to derivatives/<sub>/perf/.

Configuration

• None.
