ServiceX Client Library

Client access library for ServiceX

Introduction

Given you have a selection string, this library will manage submitting it to a ServiceX instance and retrieving the data locally for you. The selection string is often generated by another front-end library, for example:

• func_adl.xAOD (for ATLAS xAOD’s)

• func_adl.uproot (for flat ntuples)

• tcut_to_castle (translates TCut like syntax into a servicex query - should work for both)

Prerequisites

Before you can use this library you’ll need:

• An environment based on python 3.7 or later. 3.11 is highest supported at the moment.

• A ServiceX end-point. This is usually gotten by logging into and getting approved at the servicex endpoint. Once you do that, you’ll have an API token, which this library needs to access the ServiceX endpoint, and the web address where you got that token (the endpoint address).
