Pressing Cmd-Delete (OS X) or Ctrl-Delete (Linux and Window) will clear all modules from all signal chains.

Setting parameters

Most modules have a straightforward set of parameters that appear in the editor. Although the signal chain becomes locked while data acquisition is active, it's possible to edit parameters at any time. Parameter changes are not currently tracked, so be careful about changing parameters while you're recording.

Opening/saving the signal chain.

Use Cmd-S/Ctrl-S (or the "File" drop-down menu) to save the signal chain. It must have an .xml extension.

Use Cmd-O/Ctrl-O (or the "File" drop-down menu) to open a previously saved signal chain. It must have an .xml extension in order to load.

Most, but not all, modules will save their internal settings. For safety purposes, assume that any module will not reload its settings until you confirm that it does. If settings are not being loaded properly for a particular module, feel free to submit an issue on GitHub.


  • The file selector within the control panel (hidden by default, exposed with the arrow button). This determines the location of the saved data, as well as the strings to prepend or append to the data folder. If data has already been recorded, pressing the "+" button next to the file name automatically generates a new data folder.
  • The channel selector drawer within each module editor determines which channels will be saved. By default, only continuous channels from source nodes and events from any node are saved. To save continuous channels from a any other particular module, first open the drawer by clicking the vertical lines on the right side of the module editor, then switch to the "REC" tab and highlight the channels you wish to save. It's possible to save a signal after every step in the processing pipeline, but we wouldn't recommend doing this unless you have a very fast machine with a lot of free disk space. At the moment, all channels must be saved at the same sample rate, but we're working on a way to downsample LFP channels.


For information on exactly what is saved, check out the Data format wiki page.

Audio monitoring

Configuring the audio monitor is similar to setting up recording. By default, nothing is passed to the monitor. In order to listen to a particular channel, open the channel selector drawer and switch to the "AUDIO" tab. Any highlighted channels will be sent to the audio monitor. The volume of the audio monitor (and destination of the audio output) can be configured in the control panel.

Submitting issues

In the case of a crash, it's important to replicate what you did. If you can do that, and you don't know how to fix it yourself, go ahead and submit an issue describing the problem. Include your operating system and machine specs if you think it might be relevant.
