Program # 1: Wave_clus: Unsupervised
spike detection and sorting of extracellular multiunit recordings. It uses
wavelets and Super-paramagnetic clustering. The code is described in:
Unsupervised spike detection and sorting with wavelets and superparamagnetic clustering.

Neural Computation 16, 1661-1687; 2004.
Program # 2: EP_DEN v2 (runs under matlab): Denoise the single trial evoked potentials from the background EEG. It is based on a wavelet multiresolution decomposition using biorthogonal B-Splines.
Program # 3: SPECT (runs under
matlab)
Given a 1 column input ascii file, calculates its Windowed Fourier Transform
and then calculates the power spectra and the
and Kulback-Leibler (relative) entropies. It also calculates the relative
band intensity ratio (RIR). It can be tested with dataset #
3.
