Hi Ezra, thanks for this, I'm having difficulty loading in the submodule because of the colons in the 'kmeans/333/LC-Bruker maXis QTOF: Submission #10' and 'kmeans/333/LC-Bruker maXis QTOF: Submission #11' folder names and because I'm on a windows machine. Could you adjust the folder names, maybe also removing the hashes. Alternatively, the way we've been adding notebooks so far, is even if they have an existing repository we've been creating standalone repositories to house them with the naming convention 'ds-toolbox-notebook-dsfp-pyexplorer', then that repository only contains the necessary files for rendering the notebook and generating relevant environments (e.g. https://github.com/NERC-CEH/ds-toolbox-notebook-biascorrection/tree/2c6596f25e5ccdc07e193896b6fe7e4d371e3ebf).

Thanks Jez, unfortunately the entire repository is needed run the notebook right now, so i'll just edit the folder names for the time being

Hopefully that's fixed the issues!

Looks great, thanks. One minor thing to flag is that one of the links in the header of the notebook has a double h in http: {bdg-link-info}Notebook Repository hhttps://github.com/NERC-CEH/DSFP-PyExplorer
