[FieldTrip] automatic channel rejection

[Aitor Egurtzegi]

Hi Diego,

Thanks for your message. Is it possible to reject the trials / channels 
by giving a list of indices to a function, just like when running 
ft_rejectcomponent, where you reject components by passing a list of the 
components to be rejected to the cfg.component method?

Best,
Aitor
