canSAS-2012

Meeting of canSAS working groups

Purpose

Work on specific matters important to the canSAS community as decided in previous conference calls. It is expected that those attending this working session will already have strong foundation and understanding and will come ready with knowledge, tools, and ideas to make significant progress during the event. The specific projects and tasks, as well as the list of participants, are described on this wiki and will be revised as the event draws near.

The three main themes are:

• Treated data format - developing a standard for multidimensional treated data and resolving issues that arise with the 1-d standard and its implementaion.
  • Discussion Page : 2012 Data Discussion
• Standardisation - intercomparison of measurements and software for data reduction and analysis so as to assess experimental and intstrumental reliability
  • Discussion Page : 2012 Standards Discussion
• Development of a Global SAS web portal. This should be a general point of entry for the community to find information about small-angle scattering.
  • Discussion Page : 2012 Web Discussion

This page provides discussion of the themes, preliminary work and ideas : 2012 Discussion

Outcomes

• 2-d data format
• A plan for standards
• Global SAS Web Portal
• presentation at SAS2012

Dates

• 2012 July 28 - 31 (Saturday - Tuesday, inclusive)

Meeting Location

Uppsala University
Building: Angstrom Laboratory [1]
Room(s): TBA

We plan to hold some web based sessions during the meeting so that people in the broader canSAS community that are unable to attend in person can participate in some of the discussions during the meeting.

Planning

Business Matters

• Re-enunciate purpose and benefits of a standard reduced data format
  • 1D Format
  • agree a proposed foreign namespace extension of the current 1D standard (required to enable, for example, t-o-f instruments to store auxillary wavelength-dependent non-I(Q) data in the same output files)
  • 2D Format
  • define minimum necessary for reduced data
  • suggest format framework (NeXus extension, canSAS 1D extension, other) with brief discussion of the reason for the choice (including options considered, pros and cons of each, and final weighing)
  • Guide to how to make implementation easy.
  • Create straw format suitable for test/demonstration use and convert some test data for such a demonstration.
  • Provide a plan for presentation at SAS 2012

More details and suggestions are on the Discussion Page: 2012 Data Discussion .

• Standards
  • Purpose and goals: Intercomparison of data measured on the same sample with different instruments and different techniques (SAXS, SANS, light scattering etc.) can prove valuable in a number of ways. In particular it aids understanding of details of the experimental methods and it can help assess reliability. In a similar way, looking at results of data reduction or analysis generated with different software can provide valuable information about performance and verification of methodology. Specifically these activities should:
  • We will discuss what types of tests are interesting/important, intensity, resolution etc.
  • Some other related issues: Inelastic, Multiple scattering, Wavelength contamination, Detector efficiencies at different wavelengths
  • Outcomes needed are:
    • A written plan to sustain long term effort in this area
    • This should describe how to seed, co-ordinate and publicise “ad-hoc” projects ,
    • Assess how frequently exercises can be undertakem
    • Define good ways to disseminate/share results. This will including “advertising” projects and using them as input for other activities.
  • We should aim to define a list of 2 or 3 projects for work in the near term. This should include a plan of action and participants for each.
  • We shoud have a plan for presentation at SAS 2012. (This might just be an announcement of the plan and see who wants to participate?.)

More details and suggestions are on the Discussion Page: 2012 Standards Discussion

• Global SAS Web Portal
  • define scope, purpose, and goal of portal
  • list content type to which such a portal should give access.
  • Suggest method for hosting
  • Build a working straw landing page prototype
  • Build at least 2 or 3 subpages and/or designs on paper
  • plan for presentations
    • SAS 2012
    • SAS commission
