- this also fixes a bug where images would fail due to the tigris
package not being able to load
- i couldn't find the exact problem, but loading the sf package ahead of
time explicitly seemed to avoid the failure, but a warning message still

DeGAUSS is a decentralized method for geocoding and deriving community and individual level environmental characteristics while maintaining the privacy of protected health information. It is a standalone and versatile software application based on containerization. This means that geomarker assessment is reproducible, standardized, and can be computed on at scale. Importantly, DeGAUSS is executable on a local machine -- it does not require extensive computational resources and PHI is never exposed to a third party or the internet, making it ideal for geomarker assessment in a multi-site study. Please see detailed documentation within the wiki:

Currently Available Images

Please see for guidelines on how to contribute to the development of DeGAUSS. Pull requests for new containers using the DeGAUSS framework are always welcome but early visibility is highly encouraged; we often create containers that are not yet publicly available and would love to still work together. Automated tests for containers are conducted through Travis, see .travis.yml for details.
