[Eeglablist] Artifact rejection by ICA for continuous data

[Makoto Miyakoshi]

Dear Nasrin,

for future analyses on visual segments.

Do you mean you need to replicate a method described in a published paper
or something? If that's the case, you have no choice, you just need to
replicate what is described.

If you mean you need to repeat a process for all subjects etc, AND you want
to preprocess continuous EEG data, you may want to try this:

Between 5 and 6, use clean_rawdata().
http://sccn.ucsd.edu/wiki/Plugin_list_process
It has ASR (Artifact Subspace Reconstruction). This is a very smart
algorithm you may want to try.

Thus you can clean your continuous data!
