Sorry in advance if this has already been asked/listed somewhere, but I have been unable to find this information. Is there a way to access the individual .hdf5 files in the interactive Jupyter Lab notebook (https://www.tng-project.org/data/lab/), for example if we want the stellar assembly history or galaxy morphology data only (not from the fof or snapshot files)? If there is, what's the path name? I have tried looking in the folders in '../sims.TNG/TNG100-1/output/' and '/sims.TNG/TNG100-1/postprocessing/', as well as '/sims.other' (which was empty), and none of them had the .hdf5 files.
Thank you in advance for any help

Hi Alice,
All of the "supplementary catalogs" would be found in the postprocessing/ subdirectory under a given simulation.
However, not all are available in the Lab. I have just tried to make some of the most common (and biggest) available.
If there is something in particular you need, I can try to think about adding it. The alternative is simply to download it, into the Lab, with e.g. a wget command.

Hi Dr. Nelson, thank you so much for your reply. I am trying to look at the stellar assembly histories for the simulations, which doesn't seem to be in the postprocessing/ subdirectory (unless it's under a different name?), and I am worried about Jupyter Lab crashing if I use the "wget" command since the files are ~17GB in size in total (why I didn't want to download and process them locally). Is there a way around this?
Thank you again for your help

I have now added the postprocessing/released sub-directory to all simulations in the Lab. Inside you will find the Stellar Assembly catalog, among others.

Thank you so much Dr. Nelson! That'll be really helpful for studying galaxy-halo evolutions
