A Python Socket.IO server that allows any Socket.IO-compliant application to communicate with manipulators used in electrophysiology experiments.
Electrophysiology Manipulator Link
The Electrophysiology Manipulator Link (or Ephys Link for short) is a Python Socket.IO server that allows any Socket.IO-compliant application (such as Pinpoint) to communicate with manipulators used in electrophysiology experiments.
Currently, Ephys Link only supports Sensapex uMp-4 Micromanipulators and New Scale 3-axis manipulators. However, this platform is designed to be extensible to other manipulators and more may be added in the future.
For more information regarding the server's implementation and how the code is organized, see the package's development documentation.
For detailed descriptions of the server's API, see the API reference.
- Python 3.8+ and pip.
- An x86 Windows PC is required to run the server.
- For Sensapex devices, the controller unit must be connected via an ethernet cable and powered. A USB-to-ethernet adapter is acceptable. For New Scale manipulators, the controller unit must be connected via USB and be powered by a 6V power supply.
- To use the emergency stop feature, ensure an Arduino with the StopSignal sketch is connected to the computer. Follow the instructions on that repo for how to set up the Arduino.
Using a Python virtual environment is encouraged.
Create a virtual environment by running
python -m venv ephys_link
Activate the environment by running
A virtual environment helps to isolate installed packages from other packages on your computer and ensures a clean installation of Ephys Link
NOTE: Ephys Link is an HTTP server without cross-origin support. The server is currently designed to interface with local/desktop instances of Pinpoint. It will not work with the web browser versions of Pinpoint at this time.
Install for use
Run the following command to install the server:
pip install ephys-link
Update the server like any other Python package:
pip install --upgrade ephys-link
Install for development
Clone the repository.
Run the following command in the root directory of the repository to install the package along with development tools:
pip install -e .[dev]
Run the following commands in a terminal to start the server for the desired manipulator platform:
|New Scale via Pathfinder HTTP server||
There are a couple additional aliases for the Ephys Link executable:
By default, the server will broadcast with its local IP address on port 8081. Copy this information into Pinpoint to connect.
For example, if the server is running on the same computer that Pinpoint is, use
