You can run two calculations and import the paths and scale the contributions from each site. There are a lot of examples and this has been discussed before on the mailing list if you search. 

Hope that helps,

One is 6 Co-O coordinated octahedral site, and another one is 4 Co-O coordinated tetrahedral site. When we run the Feff calculation, we can only use one Co site to do the calculation once, and we can only get one site coordination by one calculation. However, the EXAFS will tell us the average local structure. How could we use these two different calculation paths to do the fitting?
