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
