[FieldTrip] Data prewhitening

[jan-mathijs schoffelen]

Hi Andrea,

As a follow up to my previous mail. There even seems to be a cfg.method = 'white' in ft_componentanalysis. As an addition to Roemers suggestion: if you want to spectrally whiten your data, his approach can be used. I interpreted your question as that you want to achieve spatial whitening. 

Best,

JM
