Scientific Filesystem in CharlieCloud

A new user to CharlieCloud (<–me) and running a workflow that is implemented with the Scientific Filesystem, and tested with Docker and Singularity. Can I figure out, during this recording, how to map it to CharlieCloud? Let’s find out!

TLDR, it comes down to:

Charliecloud

  ch-run -b data:/scif/data /var/tmp/snakemake.ch -- /bin/bash
  cd $HOME/Documents/Dropbox/Code/scif/examples/snakemake.scif  
  export PATH=/opt/conda/bin:$PATH  
  snakemake all

Singularity

  singularity shell --bind data/:/scif/data snakemake.simg
  snakemake all

Docker

   docker run -v $PWD/data:/scif/data:z -v $PWD:/working_dir -it -w /working_dir --entrypoint /bin/bash vanessa/snakemake.scif
   snakemake all

And the CharlieCloud (that looks complex) is likely not needing all of those lines (this is due to my inexperience of just an hour or two using it). This could probably be run externally (without shelling in) given that I can export the path properly. Super cool!! I promise to write this up more robustly, this is just a “quick and dirty” for now :)

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/164345 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
