Hellinger Tool: "Calculate uncertainties" fails with Python error "Unknown error" (Calculate pole works)

Q&A
1

Hi,
I’m using the Hellinger Tool in GPlates to estimate an Euler pole. Calculate pole works correctly, but Calculate uncertainties always fails with:

Python error: “Unknown error.”

When I click Calculate uncertainties, the output file (e.g., *_results) is truncated to 0 KB (it has contents after Calculate pole). Also, Show details becomes empty. This suggests the uncertainties routine starts writing but crashes before completion.

Could you advise what conditions might cause the uncertainty calculation to fail?
If needed, I can provide a minimal sample dataset (pick files) that reproduces the issue.

Thanks.

Environment / Versions

  • OS: Windows 11

  • GPlates 2.5.0 (Windows): fails at Calculate uncertainties

  • GPlates 2.2 (Windows, another computer): same failure

  • GPlates 2.1 (Windows): Calculate pole does not work at all

What works / what fails

  • :white_check_mark: Calculate pole works and computes the Euler pole.

  • :cross_mark: Calculate uncertainties always fails with “Unknown error.”

Notes

  • Output path is a simple ASCII path (e.g., C:\hellingertester\).

  • The failure happens even with simple and clean picks (no complex geometry).

Hi Shin,

Thanks for reporting that, and apologies for the delay replying.

It might be a Python 2 vs 3 issue similar to here but in a different area.

Yes, if you can send a minimal sample dataset that reproduces the issue then I’ll take a look (you can click on my name andMessage me directly).
