ICA for SPM

[neurofractal]

Let's get some ICA working for SPM:

Example Fieldtrip Code for OPMs

Currently finding it best to provide a TAN-only layout for easier interpretation of components

fastica

• Extra functions required in SPM: https://github.com/fieldtrip/fieldtrip/tree/master/external/fastica
• ft_componentanalysis checks for the fastica scripts using ft_hastoolbox on line 501

runica

• Extra function required in SPM: https://github.com/fieldtrip/fieldtrip/blob/master/external/eeglab/runica.m (seems to be ONLY this script required rather than the whole folder)
• ft_componentanalysis checks for the fastica scripts using ft_hastoolbox on line 535

Plotting

For simple plotting of independent components:

cfg.viewmode = 'component';
ft_databrowser(cfg, comp)

For fancier plotting see: i) ft_icabrowser (though I found this buggy) ii) Rob's tutorial script 2 for custom code
