[Eeglablist] Using LIMO EEG with only one or two electrodes

[Bryan Hall]

Hello Cyrille,

This is slightly off topic, but can I ask:

1. Which Muse Device are you using?
2. What specifically you did to reference?

I am working with a Muse S device and there is a 5th channel that you can enable that sounds like a reference channel, but the data does not look right to me for use as a reference.

This makes calculating electrode neighborhoods irrelevant (and impossible). However, it seems that even for first-level analysis, LIMO requires at least 3 channels, or it won't create limo_gp_level_chanlocs.mat, which is needed down the line. Is there a way to have an empty neighborhood in limo_gp_level_chanlocs  and only temporal clustering (similar to how FieldTrip handle this?).
