About The Project

Getting Started

Prerequisites

Before the installation process, the following things need to be installed:

• python3.9
• pip ($ wget https://bootstrap.pypa.io/get-pip.py)
• [email protected] ($ pip install virtualenv==20.7.2)
• git

Installation

1. Clone the repo

$ git clone https://github.com/UVA-DSA/OpenAPS-Glucosym-3.9.git

2. Virtual environment

• A virtual environment need to be set up inside ./OpenAPS-Glucosym-3.9/:

$ cd ./OpenAPS-Glucosym-3.9   
$ virtualenv --python=/usr/bin/python3.9 ./venv/ #set up a virtual environment that uses python3.9   

• To enter the virtual environment, use the following command:

$ source ./venv/bin/activate

• To quit the virtual environment, use the following command:

(venv)$ deactivate

• Note: The virtual environment needs to be activated while doing the following steps.

3. Run the auto-install script

(venv)$ chmod u+x ./closedloop3.9-setup.sh
(venv)$ ./closedloop3.9-setup.sh

• After finishing the above steps, please close the current terminal window.

Simulation Workflow

Setting up Glucosym

First, open a terminal window and run the following commands:

(venv)$ cd ./OpenAPS-Glucosym-3.9   
(venv)$ source ./venv/bin/activate   
(venv)$ cd ./glucosym   
(venv)$ npm start   

Then, open a browser and navigate to http://localhost:3000.

Initializing and running OpenAPS closed loop

Open another terminal window and initialize OpenAPS:

(venv)$ cd ./OpenAPS-Glucosym-3.9     
(venv)$ source ./venv/bin/activate   
(venv)$ cd ./openaps3.9     
(venv)$ python initialize.py [initial bg]  

Next, change the initial bg of the selected patient on the glucosym server and run the closed loop simulation:

(venv)$ python updated_ct_script_iob_based.py [number of iterations]  

• Note: Changing the patient insulin_sensitivities, bg_targets, or basal_profile files stored under ./openaps3.9/settings/ will affect the simulation result. You may want to change it if for simulation on real datasets.

Collecting output data

Run the following command:

(venv)$ python updated_collected.py

The output data should be collected in a file called data.scv under the OpenAPS directory.
