-**Note:** To work with SPRAS in HTCondor, it is recommended that you build an Apptainer image instead of using Docker. See [Converting Docker Images to Apptainer/Singularity Images](#converting-docker-images-to-apptainersingularity-images) for instructions. Importantly, the Apptainer image must be built for the linux/amd64 architecture. Most HTCondor APs will have `apptainer` installed, but they may not have `docker`. If this is the case, you can build the image with Docker on your local machine, push the image to Docker Hub, and then convert it to Apptainer's `sif` format on the AP.

 There are currently two options for running SPRAS with HTCondor. The first is to submit all SPRAS jobs to a single remote Execution Point (EP). The second
 is to use the Snakemake HTCondor executor to parallelize the workflow by submitting each job to its own EP.
