The container provided here (and built in CI) contains all of the pipeline software used in GReX. Running software like this is in lieu of using Guix, as that might be tricky if one isn't on a Linux machine (i.e. MacOS).
We build containers in CI, so no need to build on your own. As most of the software needs to use the GPU, make sure you setup the NVIDIA Container Runtime.
To get our image on your local machine, simply:
docker pull ghcr.io/grex-telescope/docker:main
To make sure everything is working, run the dedispersion test with
docker run -it --gpus all ghcr.io/grex-telescope/docker:main testdedisp
Assuming that threw no GPU errors, you should be good to go!
