I created TF maps from EEG segments from which I created an average TF map. Note that I marked some EEG channels of the segments as bad before I created the average TF map. I am able to see the frequency plot of single channels.
But as soon as I intend to look at all channels together, I get an "Array index out of bounds" message "Index in position 1 exceeds array bounds (must not exceed 21)."
I am also not able to plot the brain topography because of this. Can you please provide a resolution for this.
