**Q:** I tried to compile corsika and I get an error about missing `modules/conex` and/or `modules/data`<br>
**A:** The code is meant to be checked out using the `git clone` command (see [README instructions](https://gitlab.iap.kit.edu/AirShowerPhysics/corsika/-/blob/master/README.md#compiling)). If you downloaded a zip or tar file, you will need to instead use the `git clone` command instead with the `--recursive` flag.
**Q:** I have run the shower simulations and I don't know how to visualize the outputs. The output files are in a .parquet format in several folders: `energyloss`, `particles`, `profile` and `trakcs`. What type of information are written in these .parquet files and how can I read them?
**A:** Something something python script. Point out to notebook from Max?
