The Scientific Filesystem (scif) is an organizational format that supports exposure of executables and metadata for discoverability. The format includes a known filesystem structure, a definition for a set of environment variables describing it, and functions for generation of the variables and interaction with the libraries, metadata, and executables located within.

Here we show that interaction with a scientific filesystem is exactly the same for a Docker image vanessa/scif and a Singularity image, scif-cli. They are generated from a simple recipe
