Hi,
 
I have Mn XAS data and I am trying to export this XAS data by using "File", "Save marked group as" and "norm E". My Mn XAS data shows some spikes around 7150eV other than main Mn K edge peak due to some Fe impurity. So it is hard to fit post edge and I have ticked "Flatten normalized data" to get a straight line post edge. After doing this I can see an almost straight line post edge in the Athena preview graph but when I export ASCII data to plot in OriginPro etc it seems like data is being exported with out "Flatten normalized data".
I have attached relevant information. Am I missing some point or is it a software bug? 
 
Thanks
