can't find challenge data

[mehrhardt]

I downloaded the github repository of the challenge and a docker container (docker run --rm -it -v data:/mnt/share/petric:ro ghcr.io/synerbi/sirf:edge). NB: I noticed that the usage was much simpler than described by David here. Is this video outdated now?

I attached the image to VScode. Somehow the preinstalled conda environments didn't work with my interactive python sessions. This was "easily" fixed by creating a new environment and installing some dependencies (numpy, tensorboardx, deprecation, cil).

When running $python petric.py I received an error which I think is due to the data being missing:

to get prompts and other necessary data one needs to run download_Siemens_mMR_NEMA_IQ.py (if this data has not been downloaded already) and prepare_mMR_NEMA_IQ_data.py

[KrisThielemans]

No, we don't anymore. The data sits on the HTTPS server, all prepared.

The -v data:/mnt/share/petric:ro in your command should be modified really...

i.e. if you download https://petric.tomography.stfc.ac.uk/data/ to /some/folder/data then you need -v /some/folder/data:/mnt/share/petric:ro

I've documented this in #25 and also I'm currently zipping the folders in https://petric.tomography.stfc.ac.uk/data/ so it's easier to download in one click
