Help for a new scientist

Hi ,

I am pretty new here. I thank the entire community for making something like this. My question may be a bit very amateur, I am trying to understand the datasets that are provided by the Open Catalyst. The .extxyz files provided have data about the free energy and the position etc. Can someone briefly explain the file system of this project? I am trying to get information about a few metallic catalysts on oxidation reactions, so which approach should I take? Thanks in advance.

Thanks,
Felix
