Offline Sorter v4 now available

  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. 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. 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

  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. Our spike sorting software can also perform spike extraction on continuously recorded neural data using a variety of different thresholding methods. OFS allows sorting verification through a variety of displays and can calculate cluster separation statistics and sort quality metrics. The sorted spikes can be exported in several formats for subsequent analysis

Powerful waveform viewing and sorting

Box sorting as a pair of time-level windows
 
Waveform selection in time-voltage space
 
Template matching algorithm
 
Tetrode and Stereotrode waveform extraction and sorting using any method
 
Unit cross-correlograms and ISI plots
 
Waveform density plots in 2D or 3D in any feature space
 
Waveform alignment
 
Interval invalidation and artifact removal
 
Raster displays of spikes and continuous data
 
Printable Sorting Summary View with export to PowerPoint®
 
Waveform features and statistics can be easily exported to MATLAB®, Excel® or text file
Export of sorted data to NeuroExplorer®

 

Save and recall particular sorting instances for a selected channel (useful for comparisons)
 
Time segmentation, adaptive sorting methods, and time-dependent analysis
 
Divide each file into time segments and view and sort waveforms from each time segment separately
 
Clusters vs. Time View to show how clusters evolve as a function of time
 
Sort Quality View vs. Time Segment Graph View to display how the sort quality changes through the file
 
Adaptive template sorting, with the templates changing over time to follow the waveform as it evolves
 
Template vs. Time View to display how the template adapted through the file
 
Semi-automatic and automatic sorting
 
 Enhanced automatic sorting methods with systematic scanning through parameter space and graphs displaying the sort quality metric as a function of the parameters that were varied; select the best sorting according to a selected sort quality metric
 
 Automatic sort scan results for each channel can be saved to and loaded from .SCAN files. Together with the new batch mode scan commands, this process will allow the running of certain sorting scans overnight, followed by manual reviewing and selection of the most appropriate sort for each channel
 
 Automatic cluster selection in feature space using Valley Seeking or T-Distribution Expectation Maximization (E-M)
 
Semi-automatic cluster selection in feature space using K-Means or Standard E-M
