Extra-cellularly recorded signals by single or multi electrodes contain the spike events of a number of adjacent or distant neurons. Spike-sorting methods are techniques to sort detected multi-unit activities into spike trains of individual neurons and important step for analysis of multi-neuron activities. "EToS" is a high performance spike-sorting system using latest technologies concerned with signal processing and machine learning and can accurately sort spikes into many neurons. Programs in EToS are all parallelized using OpenMP and efficiently calculate on the computers with multi-core processors.
Version 3 is now available.
