-To have access to the GIGA mass storage, you need to be registered as a GIGA member. If you are not a GIGA member but are collaborating with a GIGA team and need access to the mass storage in the context of that collaboration, please ask the PI of the GIGA team you are collaborating with to contact the [UDIMED/UDIGIGA](contacts). If you are a GIGA member and can't access the mass storage (despite following the procedure described below), please check with the GIGA administration (admin.giga@uliege.be)  that you have been added to the GIGA member database.
