[Eeglablist] rejected components by map ( ICA)

[James Desjardins]

Hi Karlo,

ICs are flagged for removal in the gcompreject field of the EEG.reject  
structure.

Marked components can be removed in script using the following:


EEG=pop_subcomp(EEG,find(EEG.reject.gcompreject),0);

or... if the components input is left empty, pop_subcomp defaults to  
removing the IC indices flagged in the gcompreject field. So the  
following produces the same result:

EEG=pop_subcomp(EEG,[],0);
