Some updates

What

There are some issues running the r studio tutorial on M1/M2 Macs. See rocker-org/rocker-versioned2#144 for additional details.

Why is this a problem?

The docker image that is used for the tutorial: drbueno/rstudio-single-cell:latest is 2 years old and uses an old rstudio image: rocker/rstudio. The team that manages this image has apparently fixed this issue rocker-org/rocker-versioned2#144 (comment).

The real fix here would be to rebuild the docker file locally (since it automatically uses latest) and push to docker hub - however, I've attempted this and found my self in a 🌊 of dependency errors. Perhaps another day...

Fix

Thankfully there is an alternative fix: rocker-org/rocker-versioned2#144 (comment). This involves:

• adding some parameters to docker run, namely --platform linux/x86_64.
• enabling a docker setting: Use Rosetta for x86/amd64 emulation on Apple Silicon

I've added a conditional so that running ./start automatically detects the host OS and uses the appropriate docker command.

Docker settings

These are screenshots of the docker settings that should be enabled:

Bonus

• I've also suppressed some of the deprecation warnings in the python jupyter notebook 🐍 .
• Readme improvements
