[Eeglablist] Question regarding use of interpolation function

[Stephen Politzer-Ahles]

Hi Melissa,

I generally interpolate using the eeg_interp() command, so I'm not familiar
with the GUI version. To use it from the command line, just load up your
data and make sure it's the active dataset, then at the command line type:

EEG = eeg_interp( EEG, [channels] )

where [channels] is a list of one or more bad channel numbers to
interpolate.
Then, save the dataset again.

Best,
Steve Politzer-Ahles
