aECG viewer

Abstract

This python application provides a graphical user interface to index and visualize annotated electrocardiograms stored in XML files following HL7 annotated ECG (aECG) standard. This graphical user interface requires the aecg python package that is available at https://github.com/FDA/aecg-python. 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 as well as the aecg python package 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

Prerequisite: you will need aecg-python installed. The aecg-python package is available at https://github.com/FDA/aecg-python.
Clone the aecgviewer repository from https://github.com/FDA/aecgviewer 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/aecgviewer

Install aecgviewer in editable mode so you can both use it and make changes to its source code. Installing with pip will install the rest of aecgviewer dependencies. If you do not plan to do development or debugging, then you can omit the -e flag.

pip install -e .

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/aecgviewer, you can generate a local html version of the documentation from the command line as follows:

cd ~/code/aecgviewer/docs
make html
