The software is being developed in cooperation with the ETH, the Department of Gastroenterology of the University Hospital of Zürich, and Claraspital Basel. Thanks to Andreas Steingötter, Benjamin Misselwitz, Mark Fox and Werner Schwizer.

Shiny web app to fit 13C data with R package breathtestcore. You can try the web app online. No data are stored in this online version, but you can download all results and group-pairwise comparisons for studies.

Where to find the code

• On Github: https://github.com/dmenne/breathtestshiny

• On Docker Hub: https://hub.docker.com/r/dmenne/breathtestshiny

Security

No data are stored after you close the browser, or when you stop the container.

Docker image

The image cannot be compiled on the Docker hub because the build runs out of memory in the standard configuration.

Installing Docker

• For Windows 10, you can get the installer from the Docker store. For earlier versions of Windows, use the Docker toolbox. For installation details, see here.
• Linux users know how to install Docker anyway.
• Docker should have at least 2 GB of memory; on Windows, use Settings from the Docker tray icon. If you want to build the Docker image, you need at least 4 GB and 2 cores; confusing error messages are being emitted when memory is low.

Installing breathtestshiny

• From the command line, enter the following to start the container

docker run --name breathtestshiny  --restart unless-stopped -p 3838:3838 -d dmenne/breathtestshiny

• The first startup needs some time because 1 GB has to be downloaded. Subsequent startups require only a few seconds.
• Connect to the app with your browser: localhost:3838. <- This link does not work when your read this from github or the Docker hub, only on your local installation.
