The sorted spikes can be exported in several formats for subsequent analysis. OFS allows sorting verification through a variety of displays and can calculate cluster separation statistics and sort quality metrics. Our spike sorting software can also perform spike extraction on continuously recorded neural data using a variety of different thresholding methods. Spikes are displayed as points in either two-dimensional (2D) or three-dimensional (3D) feature space, where a variety of manual, semi-automated or fully-automated clustering techniques can be applied to classify (sort) the spikes. OFS version 4 is further packed with additional new functionality including but not limited to the ability to load multiple PL2 ™ files simultaneously new L-Ratio and Isolation Distance sort quality metrics support for Band and Line sorting methods ability to name and manipulate Time Segments and save as NeuroExplorer ® files new scan modes including the ability to scan using different random initial seed clusters support for multiple spike Sources ability to display arbitrary combinations for continuous and spike data together for a channel in the Timeline View the ability to use standard deviation or Median Absolute Deviation (MAD) to calculate fit or band fit tolerances and much more. Version 4 is loaded with new sophisticated algorithms and functionality including the ability to analyze overlapping waveforms, perform signal-to-noise ratio (SNR) computations, apply high-cut filtering to continuous channels and exploit digital referencing. NEW OFS v4 is a powerful, easy-to-use tool for viewing and classifying action potential waveforms (spikes) previously collected from single electrodes, stereotrodes and tetrodes.
