Sheila reported: I have been looking at the ENA stuff in EwE6 and have found a mistake in our calculation of AMI.

Also, I am getting an error if I want to get ENA in Ecosim with PPR

Joe to Sheila: I have made correction in the AMI computation. Please, see the attached spreadsheet for the values of the newly computed AMI.

The problem that pops up when running Ecosim NA with PPR is caused by an integer overflow. I fix that problem and run the ENA again. It took an hour and half to finish the run and here is the graph display and the spreadsheet. I hope the result makes sense.

Sheila to Joe: Yes the AMI looks right now. Yes, it (Ecosim NA with PPR result) makes sense for me.
