Peak Analysis

Overview

The Peak Analysis Module for LabChart provides automatic detection and analysis of multiple, non-overlapping, signal peaks in acquired waveforms. The module can be used either offline, to analyze peaks in existing recordings, or online, to analyze peaks as they are being recorded. Users can select from one of several analysis settings available for general waveforms and specific signal types.

The Peak Analysis Module is included as part of LabChart Pro or can be purchased separately.

Features

Suitable for a wide range of signals.
Calculates and reports a wide range of peak parameters.
Graphical display of calculated parameters as continuous signals in LabChart channels in real time.
Detects positive or negative peaks.
Analysis presets suitable for general and specific types of waveforms includes:
- General Unstimulated – for peaks in waveforms without stimuli
- Evoked Responses – for monophasic peaks that follow a stimulus
- Population Spikes – for extracellular evoked responses
- Synaptic – for synaptic measurements
- Action Potentials – for intracellular neuronal action potentials
- Cardiac Action Potentials – for monophasic intracellular and extracellular cardiac action potentials
Peak Analysis Settings Dialog allows the user to modify settings including:
- Detection: Determines how stimulus artifacts and peaks are detected
- Calculations: Set boundaries for the calculation of peak parameters
- Table Options: Custom selection of calculated parameters to be displayed in the Table View
Peak Analysis Table View displays calculated parameters for all detected peaks:
- Export tab: Automatically saves Table View contents as text file that can be opened in other applications
- Settings tab: Allows selection of parameters to be displayed
- Add to Data Pad tab: copies values to LabChart’s Data Pad to allow exporting and OLE linking to other applications such as Microsoft Excel
