[FieldTrip] Data prewhitening

[jan-mathijs schoffelen]

Caro Andrea,

I think you could achieve this with ft_componentanalysis (but have never tried it myself):

try:

cfg = [];
cfg.method = 'fastica';
cfg.fastica.only = 'white';
data2 = ft_componentanalysis(cfg, data);

the fastica toolbox is in fieldtrip/external/

Check out the documentation in fastica.m

Ciao,

JM
