Usage

Running the jAEViewer application

If installation has been done correctly, you should be able to run the Java class jAERViewer to look at AER data. This application is started by the scripts located at the root of the jAER project.
* jAERViewer.exe is a Windows executable launcher that does not display the logging output.
* jAERViewer.sh is a linux bash script. Note that under linux at present you cannot use hardware interfaces.

You should then see a window like this

You can now select a hardware interface from the Interface menu and a chip type from the AEChip menu and it should start rendering events from the device (if it is putting them out, of course).

If you are using a chip or board that uses biases, you will have to load bias settings. Open the bias generator dialog using the Biases button and use the File/Load settings... menu item to open a file dialog. Biases are stored in the folder java/biasgenSettings.

Viewing data

You can play either single data files (.dat) or synchronized sets of files (.index). You can drag and drop either type of file onto a fresh AEViewer window. Or you can select the file using menu item File/Open... (shortcut "o").

See Sample AER data for some data files.

Examine the menu's for help; almost all menu items have single-key shortcuts. (e.g. r=rewind, f=faster, s=slower, etc) and most have tooltips.

Below shows an example of viewing synchronized recorded data from 3 monitor/sequencer boards during the Sevilla CAVIAR workshop in Feb 2006. The retina (left) and WTA/object chip (right) are viewed using color-time representation, while the convolution chips (middle) are rendered with excitatory=green and inhibatory=red.

Logging data

The Start logging button lets you start logging data to a file. (shortcut key is 'l'). Logging is stopped by clicking again, which pops up a dialog for the location of the data file.
