quickstats 0.4.4

A tool for quick statistical analysis for HEP experiments

Setup

Clone the repository:

git clone ssh://[e-mail]:7999/clcheng/quickstats.git

1. CERN User

To set up from lxplus, just do

source setup.sh

2. Genearl User

To set up locally, make sure you have pyROOT 6.22+ installed (using conda is recommended), and do

pip install quickstats

Important: First-time compilation

To compile c++ dependencies, do this for first time use

quickstats compile

Installing pyROOT

Simplest way to install pyROOT is via conda

conda install -c conda-forge ROOT

Command Line Tools

Run Pulls

quickstats run_pulls -i <input_ws_path> -d <dataset_name> -p <np_name/pattern> --poi <poi_name> --parallel -1 -o <output_dir>
