Below are useful links to other open-source toolboxes which are definetly worth taking a look at:
|Open-Source Electrophysiological Toolbox ( OSET)||
|WFDB Toolbox for MATLAB and Octave ( WFDB-APP)||
The WFDB-APP for MATLAB and Octave is a collection of functions for reading, writing, and processing physiologic signals and time series in the formats used by PhysioBank databases (among others). The Toolbox is compatible with 64-bit MATLAB and GNU Octave on GNU/Linux, Mac OS X, and MS-Windows.
EEGLAB is an interactive Matlab toolbox for processing continuous and event-related EEG, MEG and other electrophysiological data incorporating independent component analysis (ICA), time/frequency analysis, artifact rejection, event-related statistics, and several useful modes of visualization of the averaged and single-trial data. EEGLAB runs under Linux, Unix, Windows, and Mac OS X.
