Hello all,
I'm just getting into running halo finders (namely rockstar) using yt's astro analysis package and cannot figure out how to have it such that each successive run on of rockstar does not overwrite previous runs.
I've been following the "Running Rockstar to Find Halos on Multi-Resolution-Particle Datasets" and both the HaloCatalog.create() and the RockstarHaloFinder.run() methods seem to overwrite everything in the output directory. One obvious fix here is to just have a different output directory for each dataset, but I had thought the indexes in the rockstar output files (e.g. "halos_0.0.ascii") and the list in "datasets.txt" were there to have the results from multiple datasets housed in the same directory.
And I didn't see any obvious parameters I could pass either of the above functions to specify a desired output index.
Is this possible? Or should I just write to separate folders for each dataset?
Best,
Andrew
