Dear all,

I´m trying to deal with exafs data of a Ni-phosphate compound, using Athena/Artemis. This is a simple structure (I think), with the hexacoordinated ion surrounded  by water molecules on the first shell. The question I have concerns the negative value for e0 I´m having.

Is this a bad thing?

Maybe I´m doing something wrong?

I´ve tried some issues, as those proposed on the Shelly Kelly´s tutorial, but without success.

Can you help me, please?

Attached are an example of the Athena and Artemis projects i´m using.

Thanks a lot.

Mauricio
