Python tools for annotated electrocardiogram (aECG) files

Abstract

This python package provides basic functionality to read and index annotated electrocardiogram (aECG) files in HL7 aECG (XML) format. See the TUTORIAL for a quick introduction to examples of use.

See LICENSE and DISCLAIMER at the bottom of this document.

Installing the software

These instructions assume you already have python 3.7.7 or conda installed in your system. The use of a virtual environment is recommended.

Setting up a virtual environment (optional)

Python venv

• Setup a virtual environment. In this example, we create the aecgvenv environment in ~/code/virtenvs

cd ~/code/virtenvs
python -m venv aecgvenv

• Next, activate the virtual environment

source ~/code/virtenvs/aecgvenv/bin/activate

• And upgrade pip to the most recent version

pip install --upgrade pip

Conda (Anaconda)

Launch anaconda prompt/console (from start menu or from anaconda navigator) from the base environment. In this example, we create the aecgvenv environment using the path command line option of conda.

• Go to your project directory and create a new environment by typing:

conda create -p aecgvenv

• Next, activate the conda environment

conda activate .\aecgvenv

• Next, install python 3.7.7 in the conda environment

conda install python==3.7.7

Installing from the source

• First, clone the aecg-python repository from https://github.com/FDA/aecg-python or get a copy of the source code as a tar ball.

• Change to the directory where you have cloned or downloaded the source code

cd ~/code/aecg-python

• Install aecg-python in editable mode so you can both use it and make changes to its source code when developing other tools that use aecg-python. Installing with pip will also install aecg-python dependencies. If you do not plan to do development or debugging, then you can omit the -e flag.

pip install -e .

• Run unit tests using pytest (optional)

pytest -v

Development and deployment tips

How to build the package for distribution from the source code

To create a source and wheels distributions by typing python setup.py sdist bdist_wheel in the command line.

How to generate a local copy of the documentation

• Additional requirements

pip install sphinx sphinx-autobuild sphinx-autodoc-typehints mock autodoc myst-parser

Once you have installed the additional packages listed above and assuming you have a copy of the source code in ~/code/aecg-python, you can generate a local html version of the documentation from the command line as follows:

cd ~/code/aecg-python/docs
make html
