A. Work flow diagram illustrating the 4 phases of gRAICAR algorithm. B. An illustration of the implementation of gRAICAR algorithm using a sample data set of 3 subjects, each with 4 subject-level ICs. Phase 1 involves multiple ICA decompositions for each subject. Phase 2 involves creating a full similarity matrix (FSM). ICs are aligned based upon similarity metrics in phase 3. In phase 4, ICs are averaged based upon reproducibility matrices.
