NEW Ability to display arbitrary (compatible) combinations of continuous and spike data for a channel together in the Timeline View which replaces the need to associate channels during loading of.A low-cut filter may be applied to the continuous data prior to spike extraction. Additionally, stereotrode and tetrode spike detection is supported. Multiple methods for spike detection in continuously digitized data files can be used, including voltage threshold, signal energy and nonlinear energy. time views that show how the waveforms change and evolve. OFS also contains new time-segmented views of the waveforms with cluster vs.
Ced viewer for mac manual#
Combined with new batch mode commands, this process allows the running of various sorting algorithms, which is followed by rapid manual viewing of different sort outcomes and selection of the appropriate sort for each channel. The results of the automated scanning through sorting parameter space can be saved in a SCAN file. The parameter space for several fully automatic spike sorting algorithms can be systematically scanned with graphs displaying the sort quality metric as a function of the varied parameters. The sorted spikes can be exported in several formats for subsequent analysis.
Ced viewer for mac verification#
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.
