Hi Bruce,

Thank you for your help. Yes, it happens consistently to me, but sometimes I did the same thing and it won't happen. So I was confused.

I'm afraid I don't quite understand your answer.

To be clear, if you:

* make a fitting model * run one or more fits * re-run feff * save and close artemis

the next time you open that project file, it is *guaranteed* to be broken.

I think this might explain random problems saving fits that I've seen but could never figure out how to reproduce well enough to submit a report. I'm pretty sure this happened to me during a recent "live demo" of Artemis. Great to hear that the problem is identified! --Matt

As I said, this is a shockingly obvious avenue for failure. Until I harden the program against this, the work-around is /never/ to re-run feff after running a fit. In fact, you should /never/ re-run feff after you have started dragging and dropping paths onto the data page.

I encountered a serious problem with saving an Artermis project on my windows 8 64bit desktop. When I am ready to finish my fitting work, I click to save the log file, and go to main window to choose -File-'save project as...', and then close Artemis. But when I reopen this saved project, the Path Page lost all information for each path, and the 'Include path' button has been surprisingly unchecked for all path. The GDS page have all information there. This happened to me several times, but it seems sometime the PathPage data is saved and sometime is not, although I think I was doing the exact something.

I attached one of my artemis project file and the most recent log file

saved before I close the program. Can anyone have a look and tell me what I did wrong? As my work is proceeding, this would be a very serious problem if I cannot save my 'hardwork'.

Yanyun,

I know what is causing the behavior your are observing, but I do not know how you got to this point. In short, the problem with your project file is that the mechanism that Artemis uses to path pages to paths from the feff caluclation has become completely unhinged. Even though each path is defined in a reasonable way (in the sense of having sensible math expressions for all the path parameters), every path fails to point correctly to the feff calculation.

I was able to reproduce this problem by re-running the Feff calculation then immediately saving the project file. Is this what happened?

This is a rather obvious avenue for failure. It's suprising to me that I've never thought of this before and that no one has ever before complained about that.

I think I may be able to recover your project file -- I'll take a look and let you know. B
