Here a new, fully automated model-free optimisation protocol will be presented. This protocol, defined in d'Auvergne and Gooley (2007) and d'Auvergne and Gooley (2008c), is significantly different from all those that came before, reversing the diffusion seeded paradigm as detailed below. Within relax it is referred to as the “new protocol” or the “d'Auvergne protocol”. The later name is to allow for more advanced protocols to be developed and added to relax by adventurous users in the future. Note that for advanced model-free analysis protocols, such as this one, that multiple field relaxation data is essential.
