|---|
| 43 | ------------------ |
|---|
| 44 | This incremental release brings a series of new features and improvements, |
|---|
| 45 | and a host of bug fixes. Of particular note are: |
|---|
| 46 | |
|---|
| 47 | - Correlation Function Analysis (Corfunc) |
|---|
| 48 | This performs a correlation function analysis of one-dimensional SAXS/SANS data, |
|---|
| 49 | or generates a model-independent volume fraction profile from the SANS from an |
|---|
| 50 | adsorbed polymer/surfactant layer. |
|---|
| 51 | |
|---|
| 52 | A correlation function may be interpreted in terms of an imaginary rod moving |
|---|
| 53 | through the structure of the material. Î1D(R) is the probability that a rod of |
|---|
| 54 | length R moving through the material has equal electron/neutron scattering |
|---|
| 55 | length density at either end. Hence a frequently occurring spacing within a |
|---|
| 56 | structure manifests itself as a peak. |
|---|
| 57 | |
|---|
| 58 | A volume fraction profile \Phi(z) describes how the density of polymer |
|---|
| 59 | segments/surfactant molecules varies with distance from an (assumed locally flat) |
|---|
| 60 | interface. |
|---|
| 61 | |
|---|
| 62 | - Fitting of SESANS Data |
|---|
| 63 | Data from Spin-Echo SANS measurements can now be loaded and fitted. The data will |
|---|
| 64 | be plotted against the correct axes and models will automatically perform a Hankel |
|---|
| 65 | transform in order to calculate SESANS from a SANS model. |
|---|
| 66 | |
|---|
| 67 | - Documentation |
|---|
| 68 | The documentation has undergone significant checking and updating. |
|---|
| 69 | |

|---|
| 247 | connected to the internet, or was behind a proxy server. |
|---|
| 248 | |
|---|
| 249 | - New in Version 3.1.0 |
|---|
| 250 | -------------------- |
|---|
| 251 | - The documentation/help has had a complete overhaul including: |
|---|
| 252 | - A completely new presentation interface (Sphinx). |
|---|
| 253 | - Proof reading! |
|---|
| 254 | - Updating for latest features. |
|---|
| 255 | - A Help (or sometimes ?) button has been added to every panel, and some |
|---|
| 256 | sub panels if appropriate, linking to the appropriate section in the |
|---|
| 257 | documentation. |
|---|
| 258 | - The model help has been split so that the Details button now brings up |
|---|
| 259 | a very short pop-up giving the equation being used while HELP goes to |
|---|
| 260 | the section in the full documentation describing the model. |
|---|
| 261 | - Extensive help has also been added for the new optimizer engine (see |
|---|
| 262 | below) including rules of thumb on how and when to choose a given |
|---|
| 263 | optimizer and what the parameters do. |
|---|
| 264 | - The optimizer engine has been completely replaced. The new optimizer |
|---|
| 265 | still defaults to the standard Levenberg-Marquardt algorithm. However 4 |
|---|
| 266 | other optimizers are now also available. Each starts with a set of default |
|---|
| 267 | parameters which can be tuned. The DREAM optimizer takes the longest but |
|---|
| 268 | is the most powerful and yields rich information including full parameter |
|---|
| 269 | correlation and uncertainty plots. A results panel has been added to |
|---|
| 270 | accommodate this. |
|---|
| 271 | - The five new optimizers are: |
|---|
| 272 | - A Levenberg-Marquardt optimizer |
|---|
| 273 | - A Quasi-Newton BFGS optimizer |
|---|
| 274 | - A Nelder-Mead Simplex optimizer |
|---|
| 275 | - A Differential Evolution optimizer |
|---|
| 276 | - A Monte Carlo optimizer (DREAM) |
|---|
| 277 | - New models were added: |
|---|
| 278 | - MicelleSphCoreModel (currently residing in the Uncategorized category) |
|---|
| 279 | - Existing models were updated: |
|---|
| 280 | - LamellarPS (bug in polydispersity integration fixed) |
|---|
| 281 | - RectangularPrismModel |
|---|
| 282 | - RectangularHollowPrismModel |
|---|
| 283 | - RectangularHollowPrismInfThinWallsModel |
|---|
| 284 | - Infrastructure to allow SESANS data to be fit with models was added. This |
|---|
| 285 | will become available in a future release but can currently be used from |
|---|
| 286 | the command line with some caveats. |
|---|
| 287 | - A number of bugs were fixed including a thread crashing issue and an |
|---|
| 288 | incorrect slit smearing resolution calculation. |
|---|
| 289 | - Implemented much more robust error logging to enable much easier |
|---|
| 290 | debugging in general but particularly the debugging of issues reported by |
|---|
| 291 | SasView users. |
|---|
| 292 | - A number of infrastructure tasks under the hood to enhance maintainability |
|---|
| 293 | - Upgrade from Wx 2.8 to Wx 3.0.2 which allows several new features but |
|---|
| 294 | required significant additional rework as well. |
|---|
| 295 | - Fully implemented Sphinx to the build process to produce both better |
|---|
| 296 | user documentation and developer documentation. |
|---|
| 297 | - Restructuring of the code base to more unified nomenclature and structure |
|---|
| 298 | so that the source installation tree more closely matches the installer |
|---|
| 299 | version tree. |
|---|
| 300 | - Code cleanup (an ongoing task) . |
|---|
| 301 | - Migration of the repository to github simplifying contributions from |
|---|
| 302 | non-project personnel through pull requests. |

|---|
| 308 | floating. |
|---|
| 309 | - Five new models have been added: PringlesModel, CoreShellEllipsoidXTModel, |
|---|
| 310 | RectangularPrismModel, RectangularHollowPrismModel and |
|---|

|---|
| 324 | - A generic scattering calculator which takes an atomic, magnetic or |
|---|
| 325 | SLD distribution in space and generates the appropriate 2D |
|---|
| 326 | scattering pattern. In some cases the orientationally averaged |
|---|
| 327 | (powder) 1D scattering can also be computed. Supported formats |
|---|
| 328 | include: SLD or text, PDB, and OMF magnetic moment distribution |
|---|
| 329 | file. |
|---|
| 330 | - An image viewer/converter for data in image format; this reads in |
|---|
| 331 | an image file and will attempt to convert the image pixels to |
|---|
| 332 | data. Supported formats include: TIFF, TIF, PNG, BMP, JPG. |

| 371 | - Tools: provides a number of useful supplementary tools such as SLD |
|---|
| 372 | calculation |
|---|
| 373 | |
|---|
| 374 | - Fitting |
|---|
| 375 | - Includes a large number of model functions, both form factors and structure factors. |
|---|
| 376 | - Support P(Q)*S(Q) for form factors that flag they can be so multiplied. |
|---|
| 377 | - Supports Gaussian, lognormal, Shulz, rectangular and custom distribution |
|---|
| 378 | functions for models that need to include polydispersity or for orientational |
|---|
| 379 | distributions if appropriate. |
|---|
| 380 | - Anisotropic shapes and magnetic moment modeling in 2D allow for a non-uniform |
|---|
| 381 | distribution of orientations of a given axis leading to modeling and fitting |
|---|
| 382 | capabilities of non azimuthaly symmetric data. |
|---|
| 383 | - User can choose to weight fits or not. If using weights, the user can choose |
|---|
| 384 | the error bar on each point if provided in the file, the square root |
|---|
| 385 | of the intensity or the intensity itself. |
|---|
| 386 | - Instrumental resolution smearing of model or fits is provided with several |
|---|
| 387 | options: read the resolution/point fromt he file. Input a pinhole resolution |
|---|
| 388 | or a slit resolution. |
|---|
| 389 | - Users can define the Qrange (Qmin and Qmax) for both 1D and 2D data for |
|---|
| 390 | fitting and modeling, but not graphically. The range can be reset to the |
|---|
| 391 | defaults (limits of q in data set for a fit) with the reset button. |
|---|
| 392 | - A mask can be applied to 2D calculation and fitting. |
|---|
| 393 | - Normalized residual plots are provided with every fit. |
|---|
| 394 | - Model function help available through detail button or from the fitting panel. |
|---|
| 395 | - Simultaneous/(advanced)constrained fitting allows for fitting a single |
|---|
| 396 | data set or several different sets simultaneously with the application |
|---|
| 397 | of advanced constraints relating fit parameters to functions of other |
|---|
| 398 | parameters (including from a different set). For example thickness of |
|---|
| 399 | shell = sin(30) times the length. |
|---|
| 400 | - Models that are the sum of two other models can be easily generated through the |
|---|
| 401 | SUM Model menubar item. |
|---|
| 402 | - New Python models can be added on the fly by creating an appropriate Python |
|---|
| 403 | file in the model plugin directory. Two tools are provided to help: |
|---|
| 404 | An easy to use custom model editor allows the quick generation of new Python |
|---|
| 405 | models by supplying only the parameters and their default value (box 1) |
|---|
| 406 | and the mathematical function of the model (box 2) and generating the |
|---|
| 407 | necessary *.py file. A separate advanced model editor provides a full Python |
|---|
| 408 | file editor. Either way once saved the model becomes immediately available |
|---|
| 409 | to the application. |
|---|
| 410 | - A batch fitting capability allows for the analysis of a series of data sets to |
|---|
| 411 | a single model and provides the results in a tabular form suitable for saving |
|---|
| 412 | or plotting the evolution of the fit parameters with error bars (from within |
|---|
| 413 | the application). |
|---|
| 414 | |
|---|
| 415 | - Tools |
|---|
| 416 | - A scattering length density calculator,including some X-ray information |
|---|
| 417 | is provided. |
|---|
| 418 | - A density to vol. fraction converter is provided |
|---|
| 419 | - In application access to a Python shell/editor (PyCrust) is provided |
|---|
| 420 | - An instrument resolution calculator, including possible gravitational and |
|---|
| 421 | TOF effects is provided |
|---|

|---|
| 423 | - A kiessig fringe thickness calculator is provided |
|---|
| 424 | |
|---|
| 425 | - Plots and plot management |
|---|
| 426 | - A 3D graphing option (for 2d data/results) is provided with the view |
|---|
| 427 | controlled by the mouse |
|---|
| 428 | - 2D plots are shown with an intensity color bar. 2D Color map can be user |
|---|
| 429 | adjusted. |
|---|
| 430 | - Supports output of plot to a variety of graphic formats. Supported formats |
|---|
| 431 | include: png, eps, emf, jpg/jpeg, pdf, ps, tif/tiff, rawRGBbitmap(raw, rgba), |
|---|
| 432 | and scalable vector graphic (svg/svgz) |
|---|
| 433 | - Supports ouput of data in plot (1 or 2D) to limited data formats |
|---|
| 434 | - Multiple data sets can be loaded into a single graph for viewing (but a fit |
|---|
| 435 | plot can currently only have a single plot). |
|---|
| 436 | - Extensive context sensitive plot/fitting/manipulation options are available |
|---|
| 437 | through a right mouse click pop-up menu on plots. |
|---|
| 438 | |
|---|
| 439 | - Data management |
|---|
| 440 | - Supports 2 + column 1D ASCII data, NIST 1D and 2D data, and canSAS data |
|---|
| 441 | via plug-in mechanism which can easily allow other readers as appropriate. |
|---|
| 442 | - 2D data is expected in Q space but for historical reasons accepts the |
|---|
| 443 | NIST 2D raw pixel format and will do conversion internally. |
|---|
| 444 | - The full data and metadata available to SasView is viewable in ASCII via |
|---|
| 445 | right clicking on a data set and choosing Data Info in the DataExplorer |
|---|
| 446 | or on the plots |
|---|
| 447 | - Supports loading a single file, multiple files, or a whole folder |
|---|
| 448 | - An optional Data Explorer is provided (default) which simplifies managing, |
|---|
| 449 | plotting, deleting, or setup for computation. Most functions however do |
|---|
| 450 | not require access to the explorer/manager and can be accessed through |
|---|
| 451 | right click menus and the toolbar. The data explorer can be re-started |
|---|
| 452 | from the menu bar. |
|---|
| 453 | |
|---|
| 454 | - Data manipulation |
|---|
| 455 | - Support various 2D averaging methods : Circular, sectors, annular, |
|---|
| 456 | boxsum, boxQx and boxQy. |
|---|
| 457 | - A 2D data maks editor is provided |
|---|
| 458 | - 2D mask can be applied to the circular averaging. |
|---|
| 459 | |
|---|
| 460 | - Miscellaneous features |
|---|
| 461 | - limited reports can be generated in pdf format |
|---|
| 462 | - Provides multiprocessor support(Windows only) |
|---|
| 463 | - Limited startup customization currently includes default startup |
|---|
| 464 | data folder and choice of default starting with data manager |
|---|
| 465 | - Limited support for saving(opening) a SasView project or a SasView analysis |
|---|
| 466 | (subproject) is provided. |
|---|
| 467 | - SasView can be launched and loaded with a file of interesty by double-clicking |
|---|
| 468 | on that file (recognized extension) |
|---|
| 469 | - A data file or data folder can be passed to SasView when launched from |
|---|
| 470 | the command line. |
|---|
| 471 | - Limited bookmarking capability to later recall the results of a fit calculation |
|---|
| 472 | is provided. |
|---|
| 473 | - Extensive help is provided through context sensitive mouse roll-over, |
|---|

| 478 | 2- Downloading and Installing |
|---|
| 479 | ============================= |
|---|
| 480 | |
|---|
| 481 | *** Note 1: Much more information is available at www.sasview.org under links. |
|---|
| 482 | Look in the 'For Developers' section and particularly the wiki at |
|---|
| 483 | www.sasview.org/trac/wiki. |
|---|
| 484 | *** Note 2: If you have EXE or ZIP SasView installer, you won't need any of |
|---|
| 485 | the following. However it is highly recommended that any |
|---|
| 486 | previous versions be un-installed prior to installing the |
|---|
| 487 | new version. |
|---|
| 488 | |
|---|
| 489 | 2.1- System Requirements |
|---|
| 490 | - Python version >= 2.5 and < 3.0 should be running on the system |
|---|
| 491 | - We currently use Python 2.7 |
|---|
| 492 | |
|---|
| 493 | 2.2- Installing from source |
|---|
| 494 | - Get the source code |
|---|
| 495 | - to follow the current development version from source control use |
|---|
| 496 | git clone https://github.com/SasView/sasview.git |
|---|
| 497 | git clone https://github.com/bumps/bumps.git |
|---|
| 498 | - to install a specific version |
|---|
| 499 | |
|---|
| 500 | - Build, install and run a specific release |
|---|
| 501 | - make sure the requirements below are already installed |
|---|
| 502 | - retrieve the source from https://github.com/SasView/sasview/releases |
|---|
| 503 | - open a command line window in the 'sasview-x.x.x' directory |
|---|
| 504 | - run 'python setup.py install' |
|---|
| 505 | - run 'python sasview.py' under the 'sasview' folder. |
|---|
| 506 | |
|---|
| 507 | - Build, install and run the current development version |
|---|
| 508 | - clone the source from git; also clone bumps, which is developed in parallel |
|---|
| 509 | git clone https://github.com/SasView/sasview.git |
|---|
| 510 | git clone https://github.com/bumps/bumps.git |
|---|
| 511 | - open a command line window in the 'sasview' directory |
|---|
| 512 | - run 'python setup.py build' |
|---|
| 513 | - run 'python run.py'; this runs from the source directories, so you |
|---|
| 514 | don't have to rebuild every time you make a change, unless you are |
|---|
| 515 | changing the C++ model files |
|---|

| 553 | 3- Known Issues |
|---|
| 554 | =============== |
|---|
| 555 | |
|---|
| 556 | |
|---|
| 557 | 4.1- All systems: |
|---|
| 558 | The conversion to sasmodels infrastructure is ongoing and should be |
|---|
| 559 | completed in the next release. In the meantime this leads to a few known |
|---|
| 560 | issues: |
|---|
| 561 | - The way that orientation is defined is being refactored to address |
|---|
| 562 | long standing issues and comments. In release 4.1 however only models |
|---|
| 563 | with symmetry (e.g. a=b) have been converted to the new definitions. |
|---|
| 564 | The rest (a <> b <> c - e.g. parellelepiped) maintain the same |
|---|
| 565 | definition as before and will be converted in 4.2. Note that |
|---|
| 566 | orientational distribution also makes much more sense in the new |
|---|
| 567 | framework. The documentation should indicate which definition is being |
|---|
| 568 | used for a given model. |
|---|
| 569 | - The infrastructure currently handles internal conversion of old style |
|---|
| 570 | models so that user created models in previous versions should continue |
|---|
| 571 | to work for now. At some point in the future such support will go away. |
|---|
| 572 | Everyone is encouraged to convert to the new structure which should be |
|---|
| 573 | relatively straight forward and provides a number of benefits. |
|---|
| 574 | - In that vein, the distributed models and those generated by the new |
|---|
| 575 | plugin model editor are in the new format, however those generated by |
|---|
| 576 | sum|multiply models are the old style sum|multiply models. This should |
|---|
| 577 | also disappear in the near future |
|---|
| 578 | - The on the fly discovery of plugin models and changes thereto behave |
|---|
| 579 | inconsistently. If a change to a plugin model does not seem to |
|---|
| 580 | register, the Load Plugin Models (under fitting -> Plugin Model |
|---|
| 581 | Operations) can be used. However, after calling Load Plugin Models, the |
|---|
| 582 | active plugin will no longer be loaded (even though the GUI looks like |
|---|
| 583 | it is) unless it is a sum|multiply model which works properly. All |
|---|
| 584 | others will need to be recalled from the model dropdown menu to reload |
|---|
| 585 | the model into the calculation engine. While it might be annoying it |
|---|
| 586 | does not appear to prevent SasView from working.. |
|---|
| 587 | - The model code and documentation review is ongoing. At this time the |
|---|
| 588 | core shell parellelepiped is known to have the C shell effectively fixed |
|---|
| 589 | at 0 (noted in documentation) while the triaxial ellipsoid does not seem |
|---|
| 590 | to reproduce the limit of the oblate or prolate ellipsoid. If errors are |
|---|
| 591 | found and corrected, corrected versions will be uploaded to the |
|---|
| 592 | marketplace. |
|---|
| 593 | |
|---|
| 594 | 3.1- All systems: |
|---|
| 595 | - The documentation window may take a few seconds to load the first time |
|---|
| 596 | it is called. Also, an internet connection is required before |
|---|
| 597 | equations will render properly. Until then they will show in their |
|---|
| 598 | original TeX format. |
|---|
| 599 | - If the documentation window remains stubbornly blank, try installing a |
|---|
| 600 | different browser and set that as your default browser. Issues have |
|---|
| 601 | been noted with Internet Explorer 11. |
|---|
| 602 | - Check for Updates may fail (with the status bar message ' Cannot |
|---|
| 603 | connect to the application server') if your internet connection uses |
|---|
| 604 | a proxy server. Tested resolutions for this are described on the |
|---|
| 605 | website FAQ. |
|---|
| 606 | - The copy and paste functions (^C, ^V) in the batch mode results grid |
|---|
| 607 | require two clicks: one to select the cell and a second to select the |
|---|
| 608 | contents of the cell. |
|---|
| 609 | - The tutorial has not yet been updated and is somewhat out of date |
|---|
| 610 | - Very old computers may struggle to run the 3.x and later releases |
|---|
| 611 | - Polydispersity on multiple parameters included in a simultaneous/ |
|---|
| 612 | constrained fit will likely not be correct |
|---|
| 613 | - Constrained/simultaneous fit page does not have a stop button |
|---|
| 614 | - Constrained/simultaneous fit do not accept min/max limits |
|---|
| 615 | - Save project does not store the state of all the windows |
|---|
| 616 | - Loading projects can be very slow |
|---|
| 617 | - Save Project only works once a data set has been associated with |
|---|
| 618 | a model. Error is reported on status bar. |
|---|
| 619 | - There is a numerical precision problem with the multishell model when |
|---|
| 620 | the iner radius gets large enough (ticket #288) |
|---|
| 621 | - The angular distribution angles are not clearly defined and may in |
|---|
| 622 | some cases lead to incorrect calculations(ticket #332) |
|---|
| 623 | |
|---|
| 624 | 3.2- Windows: |
|---|
| 625 | - If installed to same directory as old version without first removing |
|---|
| 626 | the old version, the old desktop icon will remain but point to the |
|---|
| 627 | new exe version. Likewise all the start menu folders and items will |
|---|
| 628 | have the old name even though pointing to the new version. Usually |
|---|
| 629 | safest to uninstall old version prior to installing new version anyway. |
|---|
| 630 | |
|---|
| 631 | 3.3- MAC: |
|---|
| 632 | - Application normally starts up hidden. Click icon in Dock to view/use |
|---|
| 633 | application. |
|---|
| 634 | - Multiprocessing does not currently work on MAC OS |
|---|
| 635 | |
|---|
| 636 | 3.4- Linux: |
|---|
| 637 | - Not well tested |
|---|
| 638 | |
