[Eeglablist] running CSP after cleaning data with ICA

[Scott Makeig]

Michele -  You are correct that data dimension is reduced by IC removal, and
should show up as null filters in CSP. I suggest you try Christian Kothe's
BCILAB toolbox (a plug-in into EEGLAB) for a complete set of BCI algorithms
with integrated cross-validation testing, etc. (and connecting to real-time
run environments). See http://sccn.ucsd.edu/wiki/BCILAB for a complete
description.
