10. A reference library of data analysis models

24/06/2025, 13:00

For many users, one of the barriers to modern data analysis tools is the need to have a background in coding. We have begun creating a common model language to make this easier across different platforms but we also think that the creation of a library of example models would be a useful starting point for users to build an appropriate model for their system. This session will therefore:

11. Introduction to nested sampling in reflectometry analysis

Andrew Caruana (STFC), Andrew Nelson (Australian Nuclear Science and Technology Organisation)

24/06/2025, 21:00

Whilst Bayesian approaches are now common for estimating posterior distributions (to understand parameter uncertainty), data analyses that obtain the Bayesian evidence term for model selection (which of model A or B is a better way of treating the data?) are much scarcer. Nested sampling is a Bayesian statistical technique for estimating this evidence term, as well as being able to estimate...

of the possible future uses of nested sampling in reflectometry analysis

7. Orsopy and a standard model language

25/06/2025, 11:00

This session will start a discussion around the model language. The session will aim to understand what is missing from the current definition of the the language, for example, can it be adapted to improve representaion of models for biological systems.

What can be done to improve uptake?

How do we ensure all facilities give users data in .ort format.
What is the added value to...

8. A checklist for reproducible publishing in reflectometry

25/06/2025, 21:00

Following the successful sessions in previous meetings on generating advice on defining some best practice for reporting results and inputs to Bayesian analysis, we would like to begin a new initiative on publishing a checklist for reproducible publishing in reflectometry. This session will begin with a discussion on how useful and general this would be, and try to define what we think “best...

9. The round-robin sample

25/06/2025, 22:00

For neutron reflectometry we have, for quite some time, been trying to collect data on a “round-robin” sample to compare neutron instruments. This session will look at the results from this study and recruit volunteers to actually write the paper. We would also like to consider what we would need to make a similar study for Synchrotron beamlines.

1. General Discussion

26/06/2025, 10:00

We will have a general discussion session on sample environment identifying the user community needs and discussing the response of the ORSO questionnaire (30 minutes)

3. Focus session on SE types

26/06/2025, 10:30

4. Creation of list of Sample Environment for ORSO webpage

26/06/2025, 11:00

This session will focus on population of the Sample Environment ORSO webpages. We wish to build a comprehensive list of environments available at different facilities, and we hope that you will take this time with us to contribute information on available environments at facilities but also novel sample environments by research groups. We would also in general like to build educational pages...
