[Eeglablist] how to apply ICA methods on pre-clinical electrode configurations

[Scott Makeig]

Brian -

The commandline function topoplot.m has a mode in which you can plot
interpolated electrode positions specified in a rectangular grid (with
arbitrary 'missing nodes', allowing any grid shape). This can be used to
plot the IC 'maps'.

As for your main question, read the EEGLAB wiki on building an EEG dataset.
