Hi All,

Fyi.. In my current version (v4.8.8 on Mac), I can't get the Excess Uncertainty Explorer to open. I've added the two files from GitHub and "Excess Uncertainty Explorer" shows up in the "Tools" dropdown options, but fails to open.

    Hi jsetera

    Can you please tell us what is says in the Python Console when you try to open it? You can view the Python Console from the Tools menu.

    Also, you need to have a U-Pb experiment open and fully processed before you open the Excess Uncertaity Explorer".

      I just saw Bence's writeup about the Excess Uncertainty Explorer and I added the plugin (note, I had to change the reference material in the code from Z_91500 to Z_GJ1 before it would properly open).

      I noticed something strange. For zircon U-Pb, we find that the AutoSmooth spline always looks like a good fit to the standard reference data, but when I open the Excess Uncertainty Explorer tool, the spline doesn't fit the same way at all. When I view the DC206_238 data in Time Series, I see nice gradual curves as it fits the data, but in Excess Uncertainty Explorer the DC206_238 spline shows up as just a straight line much like the LinearFit spline, and thus yielding much larger jack knifed values. I don't seem to be able to add screenshots to this post to demonstrate this.

      Is this likely an artifact of the Uncertainty Explorer tool, or could it be that using the AutoSmooth spline is causing the propagated errors to be calculated wrong?

      Thanks for any comments,
      Lisa

      Here is the screenshot of how DC206_238 looks in my Experiment.

      Hi @lstockli

      Would you mind sending me an example dataset (via the support email address) so that I could see what's happening here?

      Many thanks,

      Hello,

      I recently installed the Excess Uncertainty Explorer plugin and have observed the same spline issue reported by @lstockli . I was using the DRO example dataset from the 2020 webinar. It seems specific to the AutoSmooth spline selection as other spline fits do show consistent patterns in the time series and the Excess Uncertainty Explorer tool. Has there been a solution to this?

      Thanks,

      Mike

      Hi Mike,

      We're still working on a solution. We've decided to make some improvements while we're at it, which it the cause of the delays.

      Will post here when we're finished.

      Kind regards,
      Bence
