This is the free EPX version for academics, with full content and features and restrained development tools.

This version is dedicated to collaborative research between one academic laboratory and one member of the EPX Consortium. A partial access to EPX source code is granted and therefore, a licence agreement positioning intellectual property must be signed between the research partners.

A template of the agreement must be downloaded and filled in with specific elements from the laboratory, i.e. technical contacts, scientific framework and objectives, description of the partnership with the member of the EPX Consortium... The proposal of agreement must then be sent to CEA (address in the template document) for instruction by the EPX Consortium.

In case of a positive answer (within one month after the reception of the proposal), the licence agreement will be signed by the EPX co-owners and the laboratory. As the signature procedure starts, the development tools and the needed partial source code, estimated from the technical elements given in the proposal, will be installed on one station or server of the laboratory.

This is the licensed EPX version for industrials.
