Error Message when loading 2D data
by Shih, Kuo-Chih via users 12 Jun '19

12 Jun '19

Dear SASView Help Team, I am Kuo-Chih Shih from the University of Connecticut. Dr. Mu-Ping Nieh and I are now trying to fit the 2D scattering pattern we got from the Bruker nanostar machine. Since SASView is not able to read the raw data (.gfrm) from Bruker machine, I used Fit2D to convert it to a ASCII data. However, when I try to load the file, SASView shows me the following message. I also try to convert the ASCII file to the NXcanSAS file but it gave me another error message. I also attached the SasView log file. Could you please help me to troubleshoot this? [cid:b505a9c6-94ff-4c90-8c58-2fbdd050503d] [cid:fde63226-c5ac-4997-b80c-8d6ae33ad75e]

SasView release 5.0 now out!
by Paul Butler via users 27 May '19

27 May '19

Dear SasView friends, We apologize for the delay in making this exciting announcement: On May 20th, SasView 5.0, previewed at SAS2018 in Traverse City, was finally released and is available through the website. This release marks the culmination of a multiyear effort funded through the SINE2020 project and provides the first major overhaul of the user interface. The complete restructuring of the GUI code (along with a fair amount of the rest of the code shared with 4.x) should position SasView well for the next 10 years, however it is likely that there will be some unexpected issues. Thus 4.x will continue to be updated with bugs fixes and, as necessary, feature changes in the shared code that were introduced for 5.0, but no new 4.x specific features are anticipated. At the same time, on May 20th, the 4.2.2 bug fix was released and is also available on the site. This fixes the two bugs introduced in 4.2.1: inability to load project files and 2D resolution on being applied to 1 quadrant. No other changes were made. We hope that you will take this opportunity to try out the new 5.0 version and give your feedback so work on 5.1 can be prioritized. As always contributions at any level are appreciated from testing to editing/creating documentation and tutorials to code development. Sincerely, Paul Butler for the SasView team

SasView 5.0.0-Beta2 released & 4.2.1 point release
by Stephen King - UKRI STFC 20 Feb '19

20 Feb '19

The SasView Collaboration is pleased to announce two new releases of its popular data analysis package, SasView: - SasView-5.0.0-Beta2 is the latest preview of our next-generation, Python3-based, version of SasView. This Beta2 version builds on feedback received since Beta1 debuted at SAS-2018 in October and has almost all the functionality of versions 4.2.x - SasView-4.2.1 is a point release for version 4.2.0 addressing issues with the built-in model editor and the NXcanSAS file reader, in particular, but which also adds a few other improvements. Additional details can be found in the respective Release Notes. Users with 64-bit machines are encouraged to use these versions.

Fitting 1D sector cut data
by Bei Tian - TNW 24 Jan '19

24 Jan '19

Dear members of the SASView team, I’m Bei, a user of SASView. I have some anisotropic scattering data from ANSTO, which I would like to fit using SASView. Please find an example in th e attachment. As you can see, I have the reduced and stitched 1D sector cut scattering data, and the separate, raw 2D detector signals that covers diff erent Q-range. We have in mind to fit the data with an ellipsoid or cylindrical shape, but do you have any suggestions on HOW? As far as I know, SASView (version 4.2.0) can’t fit 1D data from sector c ut, is that correct? Thank you for your help. B.

Background subtraction with multiple datasets
by Greenborg 15 Nov '18

15 Nov '18

Hello all, I have a large number (thousands) of SAXS patterns from a kinetics study which I would like to perform solvent background subtraction on, I was wondering if there is an easy way to implement this data operation for a large number of patterns all at once which all have the same background which needs to be subtracted? The background is simply reaction solvent recorded over the same q range. Many thanks, Matt Greenberg

Testing needed for SasView 4.2.0-beta
by Paul Butler 25 Jul '18

25 Jul '18

Dear users of SasView, It has been over a year since our last SasView release, and we are now pre paring for a 4.2 release. As part of that process, we have now released a 4. 2.0-Beta version, available as a “Pre-release” on the releases page at: https://github.com/SasView/sasview/releases. With 4.2 the transition to a p lugin architecture for models should be complete as should the refactor of t he orientational representation/calculation for 2D oriented particles. By n ow many of you on this list may already have been using a 4.2 development ve rsion. As we move towards a new release, we would greatly appreciate any te sting you or your friends and colleagues can do on this beta version and any feedback you can give as we prepare for the full final release of 4.2.0. For those willing and interested in contributing, note that the next code camp is being held starting September 3 this year in Lund. If interested in joining us feel free to visit the wiki at http://trac.sasview.org/wiki/Code CampVIII and drop us a line. All skills sets are welcome. Besides various le vels of coding and sysadmin skills, we also need people who can help review, edit, and create user documentation as well as work on the tutorials proje cts, verify the math etc etc. Thanks for your help Paul (on behalf of the development team)

Re: [SasView Users] Batch fitting - distribution of radius not reported
by Stephen King - UKRI STFC 06 May '18

06 May '18

Dear Benjamin, In the Batch (Results) Window, if you click Edit, and then Insert Column, y ou should get a list of undisplayed parameters. Does that list have the para meter you require? If not, can you tell us what version of SasView you are using, please, and on what platform (Win/Mac)? Kind regards, Steve King (on behalf of the developers) From: Benjamin Wahlmann <benjamin.wahlmann(a)fau.de> Sent: 05 May 2018 14:28 To: users(a)sasview.org Subject: Batch fitting - distribution of radius not reported Dear fellow SasView users, I recently started evaluating SAXS data of gamma prime-precipitates in meta ls. Since we do time-resolved studies, we have large amounts of scattering c urves, so I am using the batch fitting mode. I a, using the sphere form fac tor model and I would like to calculate the mean radius and the radius distr ibutions of those precipitates (using a Gaussian distribution function); how ever, in the batch fitting results panel, I get no report on “radius.width ” although I marked “distribution of radius” for fitting. Am I doing something wrong or is this intentional? Also, is there any way to batch fit the distribution of radius? I’d appreciate your help very much. Kind regards, Benjamin Wahlmann M.Sc.

SASView - polyspersity, mean. median
by Jaroslav Kousal 17 Apr '18

17 Apr '18

Dear Sir/Madam, I using now SASView package to analyse SAXS data, thank you for this valueable piece of software. However, I am not fully sure, which parameter of the lognormal distribution ( http://www.sasview.org/docs/user/sasgui/perspectives/fitting/pd_help.html ) is used in the sphere model ( http://www.sasview.org/docs/user/models/sphere.html ) as "radius". Is it the x_mean, x_med or x_peak? The FAQ seems to suggests that "radius" is the "x_mean" and that the distribution itself is a number distribution. Is this correct?
