Mobius Tutorial: Cahper 3 - Spike Sorter 63

3-3. Replay and analysis of acquired data

3-3.2. Analyzing the spike rate

This section describes how to analyze the spike rate with the “Spike_frequency_analysis_filter (or,

Spike_frequency_analysis)” workflow template. These Analysis templates consist of following modules

located in the Tabs of “Main”, “Spike”, “Filter”, and “Averages”.

The raw data is filtered by the selected filter menu. Spikes crossing pre-defined thresholds are

extracted. Spike frequencies of all extracted spikes are computed and graphed. Raw data can be

exported as a binary or ASCII (“CSV” formatted text) file. Waveforms of extracted spikes, time stamp,

and spike frequency charts can be saved as “CSV” formatted text file.

The [Compute Measure Averages] module calculates and graphs the spike frequency averages for the

different phases. In the “Spike_frequency_analysis” template, the replayed data is sent to [Extract

Spikes] module without filtering.
