= !SasView Code Camp V = == Introduction == The fifth !SasView Code Camp was be held at the [http://neutrons.ornl.gov Spallation Neutron Source], Oak Ridge, Tennessee from 4th to 11th October, 2016 Local arrangements were made by Mathieu Doucet with details on the [wiki:CodeCampVPlanning planning page]. == Initial Goals == The management team met on Monday afternoon just prior to the Code Camp to work on a proposed set of goals for the Camp based, as always on the [https://github.com/SasView/documents/blob/master/SasView%20Roadmap%202015-11-24.md published roadmap] but informed by the many developments and activities that have taken place since the last official update. For example the ESS contribution through its SINE2020 funding to work on refactoring the GUI, an activity targeted for 2019 in the roadmap, makes moot some of the smaller GUI enhancements envisaged earlier. Further, the final release of !SasView version 4.0, completing the work from the [wiki:CodeCampIV previous Code Camp in Delft], was released just prior to the code camp. The plan was presented to the developers and after a brief disscussion the primary goals for the code camp, which will be translated to the next update to the [https://github.com/SasView/documents/blob/master/SasView%20Roadmap.md roadmap], were agreed: * TBA from list of tickets * Add a new corfunc perspective * Added file converter to support multifile data * Integrate SESANS into the !SasView GUI * Fix Save Project when constrained fits are used * Continue work on GUI refactoring (and the clean separation of UI from computational code). * Work on increasing model coverage looking at non-overlap with SASfit models. * Begin work refactoring/clean-up of Batch fitting (to include batch operations on roi such as box sum and slices). * Finish model documentation review and formatting * Add missing documentation and documentation of new functionality * Work on improving infrastructure (build systems, 64 bit/Anaconda on all platforms of build machines, trac, licensing, etc) These tasks build on the work done for release 4.0 and are aimed at a 4.1 release in late 2016/early 2017. The major items for this release are the integration of SESANS analysis, improvements to the Save Project functionality, inclusion of some models from !SasFit, enhanced documentation and improved reliability. == Participants == || Mathieu Doucet (ORNL) ||Andrew Jackson (ESS) || Paul Butler (NIST) || Steve King (STFC) || || Ricardo Ferraz Leal (ORNL) || Piotr Rozyczko (ESS) || Jeff Krzywon (NIST) || Richard Heenan (STFC) || || Wim Bouwman (Delft) || Wojciech Potrzebowski (ESS) || Dirk Honecker (ILL) || David Mannicke (ANSTO) || || Jurrian Bakker (Delft) || || || || == Progress and Outcomes == This code camp brought 13 developers together to work for 7 days on the [http://github.com/sasview/sasview SasView] and [http://github.com/sasview/sasmodels sasmodels] code, documentation, and development infrastructure. One new developer, Dirk Honecker from ILL, joined the project. As usual the camp began with introductions and updates from all the partner labs. NIST indicated that !SasView has now surpassed the use of its old IGOR analysis package among both its users and staff and that with release 4.0 plans are being made for some local tutorials. Further with their effort at the code camps and in between from 3 staff members the feeling is that they now have a sufficient handle on the code base to not dependent on others for any critical needs. ANSTO ... ISIS indicated that they had somehow managed to hire a summer undergrad to work on the code this summer who was extraordinarily productive providing many fixes and new features to the project. Several people asked about the possibility of hiring him again and it was suggested that was not out of the realm of possibility. ILL .... SNS .... Delft has done some work on the SESANS project but mostly not progressed too much on the code since last code camp. Their hope is that they can get something into the GUI at this code camp. Finally, ESS While not slated for deployment in the next release, the work on GUI refactoring and SASfit model integration, tasks receiving the attention of the full time !SasView developers at ESS, continued at this code camp in preparation for release 5.0. As part of that effort, some review discussions were undertaken and a few other developers began to help with those tasks both to speed up the development to meet our target release but more importantly to start learning the new code base for a smooth transition as the time approaches. Of note is the ESS's SINE2020 grant which represents the first new specific funding since the UTK NSF grant ended in 2011 and is a sign of the maturation of the project, is the GUI refactoring that was started prior to the Delft Code Camp and continuing. To focus the work for the code camp, the management team made proposed we target late 2016 for a v4.1 release of the features discussed and agreed. In order to achieve this, the development team was placed in [wiki:CodeCampVWorkingGroups groups] focusing on: * New GUI * SESANS analysis integration * Sasmodels bug fixing and enhancement * !SasView bug fixing and enhancement * Documentation & Training * Developer Infrastructure === Code Stats === Over the camp [[TicketQuery(changetime=2016-10-03..2016-10-11&status=closed,group=milestone,desc=1,count)]] tickets were closed.
