Verify different stages of MLHEP processing

Check MLHEP output data files

File: check_parquet.py
Usage: python check_parquet.py in_file.parquet

The Python script contains some examples of how to read from a parquet file, print some useful information, and plot histograms.

It can be used to check MLHEP skimming, training, and application outputs by testing individual parquet files.

Compare prompt fractions calculated with different inputs or methods

Files: plot_prompt_fraction_vs_crosssec_configs.py, config_fraction_vs_crosssec_configs.json
Usage: python plot_prompt_fraction_vs_crosssec_configs.py config_fraction_vs_crosssec_configs.json

Adjust the JSON config. You can provide as many histogram files in the hists dictionary as you want. By adjusting histoname, you can plot also the non-prompt fraction.

Plot prompt fraction vs different BDT cuts

Files: plot_prompt_fraction_vs_bdt_cuts.py, config_fraction_vs_bdt_cuts.json
Usage: python plot_prompt_fraction_vs_bdt_cuts.py config_fraction_vs_bdt_cuts.json

Adjust the JSON config. Here, you provide a glob pattern to all files of interest. By adjusting histoname, you can plot also the non-prompt fraction.
