Description

To incude the possibility to choose a fixed threshold for the exclusion of motion spikes (as alternative to the threshold-free spike removal method).

Tasks

• Implement removal of spike frames from PWI using a chosen NDV threshold in function xASL_wrp_RealignASL(x, bASL).
• Write the excluded frames per scan to matfile -> HENK: was already fixed before
• Provide mean NDV before and after exclusion of the scrubbed frames -> HENK: was already fixed before
• Add new parameter to https://github.com/ExploreASL/Documentation/blob/master/source/ProcessingParameters.md

How to test

Add x.modules.asl.SpikeRemovalAbsoluteThreshold to dataPar.json (e.g., 0.05 mm)

Release notes

Add an option for absolute threshold on motion spike removal.
