The manuscript submitted yesterday contained the analysis of a Data Analysis Round Robin we did for small-angle scattering.

In short, the conclusion is that misunderstandings are making it nearly impossible to get comparable results from labs for some parameters.

If you're interested in the data, we made the results and Jupyter notebook available here: https://zenodo.org/record/7509710

I'll get on with putting the preprint up on arXiv next week I hope.

Small-angle Scattering Data Analysis Round Robin: anonymized results, figures and Jupyter notebook

The intent of this round robin was to find out how comparable results from different researchers are, who analyse exactly the same processed, corrected dataset. This zip file contains the anonymized results and the jupyter notebook used to do the data processing, analysis and visualisation. Additionally, TEM images of the samples are included.

@doc Well done on pushing this forward. Many communities could benefit from a similar approach!

@lonepair It was very interesting to do, but way more complex than I expected ("We do this not because it is easy, but because we thought it would be easy").
The results are a bit depressing to me as it means we can't compare any of the published values on size distributions that easily, and getting scientists to agree on a standard must be one of life's greatest challenges. Let's see if this'll go through review easily and then we can imagine some next steps..
