Hi Everyone,
I am currently using Fieldtrip version 20111009.
I am trying to use ICA to reject EOG artifacts. I ran a correlation
between my EOG electrodes and MEG components to find the components that
should be rejected. This variable I called "toreject", then used the
following function:
cfg = [];
cfg.component = toreject;
data_reject = ft_rejectcomponent(cfg, comp);
When I try to plot my data using ft_topoplotER, the brain activity looks
'spotty'. However, when I add the cfg.component back into the cfg structure
the activity looks correct. I have also noticed that adding this
cfg.component will change the plots after I use MEGplanar and CombinePlanar.
What am I doing wrong?
Thank you in advance
Jason
