Dear Matt,

I exchanged with you on this matter some messages in September 2017, and 
after that I exchanged also other messages with Bruce Ravel in December 
2017 and January 2018. He told me that he was very busy with its new 
beamline and had no time to adapt Artemis so that it could use feff 
8.5L. This was of course long ago. If Artemis can now use the output of 
feff 8.5L, I'm glad to know and will try it. I presume that it will be 
enough to tell Artemis the location of this feff code.

On the other hand, I do not use normally Larch, although I know about 
it. Are there advantages in using Larch instead of Artemis?

Thanks anyway for the clarification.

Best wishes,

José Carlos
