rbeb6da4 r16030b1 9 9 some significant changes from previous versions. Further, as promised, it 10 10 marks the end of support for 32 bit operating systems and is only 11 available for 64bit operating systems. With this version the change to the 12 new model API and plugins infrastructure begun with 4.0 is essentially 13 complete (though extensions are in the works and more are likely they 14 should remain backwardly compatible with previous versions of SasView). 15 NOTE: old style plugin models, including old sum|mul mocels will continue 11 available for 64 bit operating systems. 12 13 With this version the change to the new model API and plugins infrastructure 14 begun with 4.0 is essentially complete (though extensions are in the works 15 and more are likely they should remain backwardly compatible with previous 16 versions of SasView). 17 18 NOTE: Old-style plugin models, including old sum|multiply models will continue 16 19 to be supported (i.e. SasView will be able to run them) in 4.x. However, 17 20 the expectation is that such support will be removed in 5.0 and everyone 18 21 is strongly encouraged to convert their custom models to the new API. 19 Finally, the new orientation angles and orientatinal distribution is now 20 also complete. 21 22 23 Finally, the changes to orientation angles and orientational distribution 24 definitions are now also complete. 25 22 26 - Changes 23 27 - The infrastucture for calculating 2D patterns from 3D orientated objects … … 27 31 aligned objects has been completely overhauled. It now differs from 28 32 previous versions. 29 - Plugin models, including sum /multiply models, have completely migrated33 - Plugin models, including sum|multiply models, have completely migrated 30 34 to the new infrastructure. NOTE that 3.x type models as well as early, 31 35 intermediate 4.x type models, including those generated by sum|multiply … … 41 45 understanding the new orientation framework. 42 46 - Problems with the computation of magnetic scattering from some 43 objects have been rectified.

Of particular note are: 244 249 245 250 - Correlation Function Analysis (Corfunc) 246 This performs a correlation function analysis of one-dimensional SAXS/SANS data,247 or generates a model-independent volume fraction profile from the SANS from an 248 249 250 A correlation function may be interpreted in terms of an imaginary rod moving 251 through the structure of the material. G1(R) is the probability that a rod of 252 length R moving through the material has equal electron/neutron scattering 253 length density at either end. Hence a frequently occurring spacing within a 254 255 256 A volume fraction profile \Phi(z) describes how the density of polymer 257 258 251 This performs a correlation function analysis of one-dimensional SAXS/SANS data, 252 or generates a model-independent volume fraction profile from the SANS from an 253 adsorbed polymer/surfactant layer. 254 255 A correlation function may be interpreted in terms of an imaginary rod moving 256 through the structure of the material. ÃŜââ¬Å1D(R) is the probability that a rod of 257 length R moving through the material has equal electron/neutron scattering 258 length density at either end. Hence a frequently occurring spacing within a 259 structure manifests itself as a peak. 260 261 A volume fraction profile \Phi(z) describes how the density of polymer 262 segments/surfactant molecules varies with distance from an (assumed locally flat) 263 interface. 259 264 260 265 - Fitting of SESANS Data 261 Data from Spin-Echo SANS measurements can now be loaded and fitted. The data will262 be plotted against the correct axes and models will automatically perform a Hankel 263 266 Data from Spin-Echo SANS measurements can now be loaded and fitted. The data will 267 be plotted against the correct axes and models will automatically perform a Hankel 268 transform in order to calculate SESANS from a SANS model. 264 269 265 270 - Documentation 266 271 The documentation has undergone significant checking and updating. 267 272 268 273 - Improvements … … 324 329 - Old custom models should now still work 325 330 - '''NOTE:''' These will be deprecated in a future version. Old 326 327 328 331 custom models should be converted to the new model format which 332 is now the same as the built in models and offers much better 333 support. 329 334 - Custom model editor now creates new style models 330 335 - Custom model editor supports better error checking … … 337 342 - The active optimizer is now listed on the top of the fit panel. 338 343 - Linear fits now update qmin and max when the x scale limits are 339 344 changed. Also the plot range no longer resets after a fit. 340 345 - Bug fixes 341 346 - Fixes bug #511 Errors in linearized fits and clean up of interface 342 347 including Kratky representation 343 348 - Fixes bug #186 Data operation Tool now executes when something is 344 349 entered in the text box and does not wait for the user to hit enter 345 350 - Fixes bug #459 plot context menu bug 346 351 - Fixes bug #559 copy to clipboard in graph menu broken … … 642 647 ============================= 643 648 644 *** Note 1: The easiest approach to setting up the prop oer environment to649 *** Note 1: The easiest approach to setting up the proper environment to 645 650 build from source is to use conda.

In release 4.1 however only models 712 with symmetry (e.g. a=b) have been converted to the new definitions. 713 The rest (a <> b <> c - e.g. parellelepiped) maintain the same 714 definition as before and will be converted in 4.2. Note that 715 orientational distribution also makes much more sense in the new 716 framework. The documentation should indicate which definition is being 717 used for a given model. 712 718 - The infrastructure currently handles internal conversion of old style 713 714 715 716 relatively straight forward and provides a number of benefits.719 models so that user created models in previous versions should continue 720 to work for now. At some point in the future such support will go away. 721 Everyone is encouraged to convert to the new structure which should be 722 relatively straight forward and provides a number of benefits. 717 723 - In that vein, the distributed models and those generated by the new 718 719 720 also disappear in the near future724 plugin model editor are in the new format, however those generated by 725 sum|multiply models are the old style sum|multiply models. This should 726 also disappear in the near future 721 727 - The on the fly discovery of plugin models and changes thereto behave 722 723 724 725 726 727 728 729 728 inconsistently. If a change to a plugin model does not seem to 729 register, the Load Plugin Models (under fitting -> Plugin Model 730 Operations) can be used. However, after calling Load Plugin Models, the 731 active plugin will no longer be loaded (even though the GUI looks like 732 it is) unless it is a sum|multiply model which works properly. All 733 others will need to be recalled from the model dropdown menu to reload 734 the model into the calculation engine. While it might be annoying it 735 does not appear to prevent SasView from working.. 730 736 - The model code and documentation review is ongoing. At this time the 731 732 733 734 735 marketplace.736 737 core shell parellelepiped is known to have the C shell effectively fixed 738 at 0 (noted in documentation) while the triaxial ellipsoid does not seem 739 to reproduce the limit of the oblate or prolate ellipsoid. If errors are 740 found and corrected, corrected versions will be uploaded to the 741 marketplace. 742 737 743 3.1- All systems: 738 744 - The documentation window may take a few seconds to load the first time
