Not seeing content above? The web application is running on the open-source version of Shiny Server. Startup time may be extended due to server load. Visiting at different times is recommended. Contact the publication's corresponding author for persistent problems. Alternatively, see the offline setup instructions below.
For multiple values, local processing is suggested. An R package and adipose tissue models are available on GitHub. See below for local setup guidance.
Installing the R package locally is straightforward. Installation instructions are in the GitHub repository.
