[FieldTrip] ICA+frqanalysis questions

Hi all,

I'm troubled by the fact that when I use ICA for 
blinks\eyes movements removal, I remove the relevant components also 
from trials that do not contain blinks\eyes movements. In order to avoid
 this bias we thought to combine the data before ICA ("data" structure) 
with the data after ICA ("dataica" structure), only in specific trials, 
as follows:

blinks=[2 4 5 8 bla bla 156];
for ind=1:length(blinks)

To my first question: I just wanted to check that there is no problem with that, or any reason not to use it.

 issue- I use motor learning task, and I'm trying to understand what 
happens through the process, in terms of power-frequency changes through
 the process. How would you recommend that I'd use the ft_freqanalysis 
function? What method to use (or what do I need to consider when 
choosing the method field)? 

Thanks a lot,
