[Eeglablist] Channel Number After Interpolation

[Alterman, Bennett L]

Hello,

When I interpolate a channel using "Use specific channels of other dataset", the new channel number is added to the end of the channels. For example FP1 is my first channel (FPZ is channel 2), but if I remove it and then interpolate it later, it is listed as channel 58, and FPZ becomes channel 1 and the rest of the data are all shifted one channel number. When I plot the channels, they are all in the correct position on the head because it is still correctly mapped to my chanlocs file. So the head map starts with 58, then 1-57 for the remaining channels.

Is this a problem for creating my study? Or is it fine because the channels are mapped by the label (i.e., "FP1") rather than the channel number (i.e., 58)? I just want to make sure that I am not mapping channel 58 to channel 58, but am mapping FP1 to FP1 between datasets.



Sincerely,
Bennett Alterman, M.S.
