This is an example for a container that serves to make it easy to run
various metrics over an analysis of interest (the container’s main runscript).
Each installed app can be thought of as a particular context to evoke the
container’s main runscript.
# List all apps
singularity apps <container>
# Run a specific app
singularity run --app <app> <container>
# Loop over all apps
for app in $(singularity apps metrics.img); do
singularity run --app $app metrics.img
done
