[Eeglablist] How can I quantify data in EEGlab ?

[Simon-Shlomo Poil]

Dear Imtiaz,

You can quantify the EEG using a NBT toolbox (see www.nbtwiki.net), which
is also a plugin to EEGLAB. The NBT toolbox offers several ways of
quantifying the EEG in both the spatial, temporal and spectral domain, you
can also easily add your own algorithms.

Best wishes, and good luck with your research
Simon
