The Spectrum Viewer plugin is not yet available for GUI version 0.6.X.
The Spectrum Viewer plugin is not included by default in the Open Ephys GUI. To install, use ctrl-P to access the Plugin Installer, browse to the “Spectrum Viewer” plugin, and click the “Install” button.
The Plugin Installer also allows you to upgrade to the latest version of this plugin, if it’s already installed.
First, make sure the correct sub-processor is selected in the plugin editor. Then, select one or two channels to display. The first channel (A) will appear in yellow. The second channel (B) will appear in green.
You can update the selected channels, but not the selected sub-processor, while acquisition is active.
The Spectrum Viewer analyzes the incoming data in 250 ms segments, and overlays the resulting power spectra for 5 adjacent segments. The power is plotted on a log scale, and the frequency range is fixed between 4 and 500 Hz.
We are planning to add more features to the spectrum display over time.
