I have just started working on adding an option to record from voltmeters and spike detectors in Neuronify.
In the video below, you can see an early implementation of this:
By clicking the red button on the voltmeter or spike detector, the application prompts you to choose a directory to store your recordings. Once selected, the recording starts into a CSV file with the current time and date.
In the future, I will look into adding support for storing data to more common formats, such as Open Ephys, NWB and KWIK. However, I might postpone this until I find an existing library that already supports saving to all of these.
For the time being, this development happens in a feature branch of the Neuronify repository. I am hoping to finalize it and release a new version of Neuronify soon.
