    11Release Notes 
    22============= 
    3  
     3     
    441- Features 
    55=========== 
    66    - New in Version 4.2.0 
    77      -------------------- 
    8       This release heralds many improvements and a host of bug fixes, along with 
    9       some significant changes from previous versions. Further, as promised, it 
    10       marks the end of support for 32 bit operating systems and is only 
    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 
    19       to be supported (i.e. SasView will be able to run them) in 4.x. However, 
    20       the expectation is that such support will be removed in 5.0 and everyone 
    21       is strongly encouraged to convert their custom models to the new API. 
    22  
    23       Finally, the changes to orientation angles and orientational distribution 
    24       definitions are now also complete. 
    25  
     8      This point release heralds many improvements and a host of bug fixes. But there are also some significant changes from previous versions. 
     9       
    2610      - Changes 
    27          - The infrastucture for calculating 2D patterns from 3D orientated objects 
    28            has been totally re-factored. It is now more accurate and consistent 
    29            across models. 
    30          - The way that SasView defines the orientation of anisometric and 
    31            aligned objects has been completely overhauled. It now differs from 
    32            previous versions. 
    33          - Plugin models, including sum|multiply models, have completely migrated 
    34            to the new infrastructure. NOTE that 3.x type models as well as early, 
    35            intermediate 4.x type models, including those generated by sum|multiply 
    36            will continue to be supported in 4.x but will likely no longer be 
    37            supported after the move to 5.0.  Users are strongly encouraged to 
    38            migrate any custom models. 
    39          - The NeXus loader has been removed as it is superseded by the NXcanSAS 
    40            standard loader and SasView does not support the treatment of raw 
    41            data. 
     11         - The infrastucture for calculating 2D patterns from 3D orientated objects has been totally re-factored. It is now more accurate and consistent across models. 
     12         - The way that SasView defines the orientation of anisometric and aligned objects has been completely overhauled. It now differs from previous versions. 
     13         - Plugin models, including sum/multiply models, have completely migrated to the new infrastructure. ???DO WE NEED TO SAY SOMETHING ABOUT BACKWARD COMPATIBILITY OR LEGACY SUPPORT HERE??? 
     14         - The NeXus loader has been removed (as it is superseded by the NXcanSAS loader). 
    4215      - Improvements 
    43          - The accuracy/speed of some numerical integrations have been improved. 
    44          - An orientation viewer tool has been introduced to assist in 
    45            understanding the new orientation framework. 
    46          - Problems with the computation of magnetic scattering from some 
    47            objects have been rectified. Some questions remain however. 
     16         - The accuracy/speed of some numerical integrations have been improved. ???CHECK WITH PAULK??? 
     17         - An orientation viewer tool has been introduced (to assist in understanding the new orientation framework). 
     18         - Problems with the computation of magnetic scattering from some objects have been rectified. 
    4819         - The known issue with the core_shell_parallelepiped model is now fixed. 
    49          - A number of issues and inconsistencies with the creation of 
    50            sum|multiply models have been rectified. 
    51          - A Boltzmann distribution has been added for polydispersity/orientational 
    52            distributions. 
     20         - A number of issues and inconsistencies with the creation of sum|product models have been rectified (and more work is in progress). 
     21         - A Boltzmann distribution has been added for polydispersity/orientational distributions. 
    5322         - Some batch slicing options have been introduced. 
    5423         - Correlation function analysis now computes both the 1D and 3D functions. 
    5524         - There are several data loading improvements. 
    56          - There are several improvements to Save/Load Project. 
     25         - There are several improvements to Save/Load Project (with more to come). 
    5726         - There have been numerous other bug fixes. 
    5827      - Documentation 
    59            Several sections of the help documentation have undergone significant 
    60            checking and updating, particularly those relating to orientation, 
    61            magnetic scattering, and polydispersity distributions. Detailed 
    62            advanced instructions for plugin writing and some scripting 
    63            instructions have been added. 
     28         Several sections of the help documentation have undergone significant checking and updating, particularly those relating to orientation, magnetic scattering, and polydispersity distributions. 
    6429      - Other work 
    65          - A Third-Party initiative has recently succeeded in getting SasView to 
    66            run on Debian. More details at 
    67            http://trac.sasview.org/wiki/DevNotes/Projects/Debian 
    68          - With this release we have started to prepare for the inevitable move 
    69            to Python 3, which will occur with the release of 5.0 
    70          - SasView 5.0 is currently in development. The two most significant 
    71            features of this version will be (i) a move away from the present 
    72            WxPython GUIs to new, completely rewritten, Qt5 GUIs, and 
    73            (ii)implementation of the Beta-approximation for S(Q). Subject to 
    74            resources, some limited access to the latter functionality may be 
    75            available in a future SasView 4.x release. 
     30         - A Third-Party initiative has recently succeeded in getting SasView to run on Debian. More details at http://trac.sasview.org/wiki/DevNotes/Projects/Debian 
     31         - With this release we have started to prepare for the inevitable move to Python 3. 
     32         - SasView 5.0 is already in development. The two most significant features of this version will be (i) a move away from the present WxPython GUIs to new Qt5 GUIs, and (ii) implementation of the Beta-approximation for S(Q). Subject to resources, the latter functionality may be released (in a non-GUI form) in an interim SasView 4.3.0.

    … …  
    249200      This incremental release brings a series of new features and improvements, 
    250201      and a host of bug fixes. Of particular note are: 
    251  
     202       
    252203      - Correlation Function Analysis (Corfunc) 
    253         This performs a correlation function analysis of one-dimensional SAXS/SANS data, 
    254         or generates a model-independent volume fraction profile from the SANS from an 
    255         adsorbed polymer/surfactant layer. 
    256  
    257         A correlation function may be interpreted in terms of an imaginary rod moving 
    258         through the structure of the material. G1(R) is the probability that a rod of 
    259         length R moving through the material has equal electron/neutron scattering 
    260         length density at either end. Hence a frequently occurring spacing within a 
    261         structure manifests itself as a peak. 
    262  
    263         A volume fraction profile \Phi(z) describes how the density of polymer 
    264         segments/surfactant molecules varies with distance from an (assumed locally flat) 
    265         interface. 
     204        This performs a correlation function analysis of one-dimensional SAXS/SANS data,  
     205            or generates a model-independent volume fraction profile from the SANS from an  
     206            adsorbed polymer/surfactant layer. 
     207 
     208            A correlation function may be interpreted in terms of an imaginary rod moving  
     209            through the structure of the material. Γ1D(R) is the probability that a rod of  
     210            length R moving through the material has equal electron/neutron scattering  
     211            length density at either end. Hence a frequently occurring spacing within a  
     212            structure manifests itself as a peak. 
     213 
     214            A volume fraction profile \Phi(z) describes how the density of polymer  
     215            segments/surfactant molecules varies with distance from an (assumed locally flat) 
     216            interface. 
    266217 
    267218      - Fitting of SESANS Data 
    268         Data from Spin-Echo SANS measurements can now be loaded and fitted. The data will 
    269         be plotted against the correct axes and models will automatically perform a Hankel 
    270         transform in order to calculate SESANS from a SANS model. 
     219        Data from Spin-Echo SANS measurements can now be loaded and fitted. The data will

    333               custom models should be converted to the new model format which 
    334               is now the same as the built in models and offers much better 
    335               support. 
     284            custom models should be converted to the new model format which

    646    *** Note 1:  If you have a SasView installer (.EXE or .MSI), you do not need to  
    647                 worry about any of the following.  However, it is highly recommended  
    648                 that any previous versions of SasView are uninstalled prior to  
    649                 installing the new version UNLESS you are installing SasView to  
    650                 versioned folders. 
    651  
    652    *** Note 2:  The easiest approach to setting up the proper environment to 
    653                 build from source is to use Conda.  Instructions for setting up 
    654                 and using Conda can be found at: 
    655                   http://trac.sasview.org/wiki/DevNotes/CondaDevSetup 
    656                      
    657    *** Note 3:  Much more information is available at www.sasview.org under  
    658                 links/downloads. In particular, look in the 'For Developers' section.  
    659                 Also have a look at http://trac.sasview.org/. 
     603   *** Note 1:  Much more information is available at www.sasview.org under links. 
     604                    Look in the 'For Developers' section and particularly the wiki at 
     605                www.sasview.org/trac/wiki. 
     606   *** Note 2:  If you have EXE or ZIP SasView installer, you won't need any of 
     607                the following.  However it is highly recommended that any 
     608                previous versions be un-installed prior to installing the 
     609                new version. 
    660610 
    661611   2.1- System Requirements 
    … …  
    663613        - We currently use Python 2.7 
    664614 
    665    2.2- Package Dependencies 
    666         - Ensure the required dependencies are installed 
    667           - For the latest list of dependencies see the appropriate yml file in 
    668             the SasView repo at sasview/build_tools/conda/ymls 
    669  
    670    2.3- Installing from Source 
     615   2.2- Installing from source 
    671616        - Get the source code 
    672           - create a folder to contain the source code; if working with 
    673             multiple versions you might want to use versioned folder names 
    674             like 'sasview-x.x.x' 
    675           - open a command line window in the source code folder 
    676           - to get the CURRENT DEVELOPMENT VERSION from source control use 
    677               git clone https://github.com/SasView/sasview.git sasview 
    678               git clone https://github.com/Sasview/sasmodels.git sasmodels 
    679               git clone https://github.com/bumps/bumps.git bumps 
    680           - to get a SPECIFIC RELEASE VERSION from source control go to 
    681               https://github.com/SasView/sasview/releases 
    682             and download the required zip or tar.gz file. Unzip/untar it 
    683             to the source code folder. 
    684  
    685    2.4- Building and Installing          
    686         - To build the code 
    687             use 'python setup.py build' 
    688         - To build the documentation 
    689             use'python setup.py docs' 
    690  
    691    2.5- Running SasView 
    692           - use 'python run.py'; this runs from the source directories, so you 
     617          - to follow the current development version from source control use 
     618              git clone https://github.com/SasView/sasview.git 
     619              git clone https://github.com/bumps/bumps.git 
     620          - to install a specific version 
     621 
     622        - Build, install and run a specific release 
     623          - make sure the requirements below are already installed 
     624          - retrieve the source from https://github.com/SasView/sasview/releases 
     625          - open a command line window in the 'sasview-x.x.x' directory 
     626          - run 'python setup.py install' 
     627          - run 'python sasview.py' under the 'sasview' folder. 
     628 
     629        - Build, install and run the current development version 
     630          - clone the source from git; also clone bumps, which is developed in parallel 
     631              git clone https://github.com/SasView/sasview.git 
     632              git clone https://github.com/bumps/bumps.git 
     633          - open a command line window in the 'sasview' directory 
     634          - run 'python setup.py build' 
     635          - run 'python run.py'; this runs from the source directories, so you 
    693636            don't have to rebuild every time you make a change, unless you are 
    694             changing the C model files. 
    695           - if using Conda the above command will also build SasView, but you  
    696             must issue 'activate sasview' first. 
     637            changing the C++ model files 
     638 
     639        - The following modules are required (version numbers are what are used

    712681      issues: 
    713682        - The way that orientation is defined is being refactored to address 
    714           long standing issues and comments.  In release 4.1 however only models 
    715           with symmetry (e.g. a=b) have been converted to the new definitions. 
    716           The rest (a <> b <> c - e.g. parellelepiped) maintain the same 
    717           definition as before and will be converted in 4.2.  Note that 
    718           orientational distribution also makes much more sense in the new 
    719           framework.  The documentation should indicate which definition is being 
    720           used for a given model.

    721690        - The infrastructure currently handles internal conversion of old style 
    722           models so that user created models in previous versions should continue 
    723           to work for now. At some point in the future such support will go away. 
    724           Everyone is encouraged to convert to the new structure which should be 
    725           relatively straight forward and provides a number of benefits.

    726695        - In that vein, the distributed models and those generated by the new 
    727           plugin model editor are in the new format, however those generated by 
    728           sum|multiply models are the old style sum|multiply models. This should 
    729           also disappear in the near future

     697        sum|multiply models are the old style sum|multiply models. This should 
     698        also disappear in the near future  
    730699        - The on the fly discovery of plugin models and changes thereto behave 
    731           inconsistently.  If a change to a plugin model does not seem to 
    732           register, the Load Plugin Models (under fitting -> Plugin Model 
    733           Operations) can be used.  However, after calling Load Plugin Models, the 
    734           active plugin will no longer be loaded (even though the GUI looks like 
    735           it is) unless it is a sum|multiply model which works properly.  All 
    736           others will need to be recalled from the model dropdown menu to reload 
    737           the model into the calculation engine.  While it might be annoying it 
    738           does not appear to prevent SasView from working.. 
     700        inconsistently.  If a change to a plugin model does not seem to

    739708        - The model code and documentation review is ongoing. At this time the 
    740           core shell parellelepiped is known to have the C shell effectively fixed 
    741           at 0 (noted in documentation) while the triaxial ellipsoid does not seem 
    742           to reproduce the limit of the oblate or prolate ellipsoid. If errors are 
    743           found and corrected, corrected versions will be uploaded to the 
    744           marketplace.

     709        core shell parellelepiped is known to have the C shell effectively fixed
