10 Oct '25

Dear SasView Users, In anticipation of the upcoming SasView contributor camp to be held in Garching Nov 11-17 this year, the host institution requested a SasView tutorial be offered prior to the camp. This is taking the form of a two half day intermediate level SasView usage tutorial offered over zoom on Thursday and Friday October 23 and 24. The program is available at: https://indico.frm2.tum.de/event/594/ If you are interested in the program, registration is now open to anyone on a first come first served basis via the above link. Cheers Paul Butler, Annika Stellhorn, and Neelima Paul

Bug Report – Unexpected Behavior of Polydispersity in SASview v6
by Abdoltajedini, Fatemeh via users 09 Oct '25

09 Oct '25

Dear SASview Team, I would like to report a possible bug I encountered in SASview v6 related to polydispersity. Description of the issue: When I add polydispersity to a model, the scattering curve changes far more dramatically than expected. Even small values (e.g., 0.05 on radius) cause the intensity and curve shape to shift disproportionately, which does not seem physically reasonable. Steps to reproduce: 1. Open SASview v6. 2. Load the [Core-Shell Cylinder]. 3. Fit the model without polydispersity – the curve looks reasonable. 4. Add a small polydispersity (e.g., 0.05 on radius). 5. The curve changes strongly in both shape and magnitude. Expected behavior: Polydispersity should broaden or smooth features of the scattering curve, but not cause large intensity changes or unrealistic distortions. Observed behavior: Even small polydispersity values produce a strong, unrealistic effect. Environment: * SASview version: 6.x * Operating system: Windows * Data used: experimental data Thank you for your help and for maintaining this valuable software. Best regards, Fatemeh

SasView 6.1.1 Released
by Stephen King - STFC UKRI via users 03 Oct '25

Dear Members of the SasView Users List, We are pleased to inform you that we have just released an update to SasView, SasView 6.1.1, available as usual through the SasView website<https://www.sasview.org/>. This is a bug fix release rectifying some issues identified in the recent 6.1.0 release this summer. For those that prefer to build their installation from source (eg, Linux users), SasView is also available through Flatpak<https://flathub.org/apps/org.sasview.sasview>. However, it may take a few more days before 6.1.1 makes its way onto Flathub. We would also like to remind you about the SasView Contributor Camp XIV<https://indico.ess.eu/event/3800/> to be hosted by TU Munich, Garching, Germany between November 11-17th, 2025. In particular, in response to community demand the scope of this Camp has been expanded from its original focus on the needs of the Magnetic SAS and allied communities (ie, those SAS users producing more complex data than isotropic powder patterns) to now include Life Sciences. Please see the planning wiki at https://github.com/SasView/sasview/wiki/ContributorCampXIV for more information. Thank you for your continued support! And, as ever, if you would like to get involved, please see https://www.sasview.org/contribute/ for further information. The SasView Collaboration
