[Ifeffit] Including MS paths with an aggregate feff calculation in Artemis

Dear mailing list subscribers, Is it possible to perform an aggregate feff calculation in Artemis, and then perform a fit using multiple scattering paths? It appears that the aggregate feff calculation is able to successfully compute MS paths, but Artemis will not let me include these paths in a fit. I am only able to perform an (aggregate) fit using single scattering paths. Please let me know if there is anything I can do to perform an aggregate fit with MS paths. Thank you, Jamie
