6. High Level Interface: an other way to analyse data

The HLI is a supplementary interface allowing:

• configuration of an analysis from a YAML file, which allows the setup of analysis pipelines
• stable interface for the users, whatever the evolution of the low-level APIs
• usable via notebooks, python scripts (or click command lines)
