[Eeglablist] running CSP after cleaning data with ICA

[Michele Barsotti]

Hello everyone,
 I'm working on a BCI system. I have found useful to work with CSPs but to
have good spatial filter the data must be cleaned.
I clean data manually with ICA.
When I run CSPs algorithm after ICA cleaning the last common spatial filter
are all zero.
I think that this happens because with ICA cleaning decrease the rank of
matrix data.
It's right?

Other question: Can anyone tell me where I can find a good algorithm for
CSPs?

Thanks in advance
