Configurer GANGA au LPSC

Installation

Pour l'instant, GANGA n'est pas installé sur l'UI du LPSC. Vous devez donc vous faire votre propre installation dans votre répertoire home.
La ​procédure d'installation est décrite sur le site officiel de ganga (Local Installations)

Configuration

GANGA est configuré par défaut, mais vous pouvez créer et modifier un fichier .gangarc pour le personnaliser.

Création du fichier .gangarc
