2. canSAS - a brief history
canSAS: Collective Action(Aid) for Nomadic Small Angle Scatterers
Grenoble Feb – Looking for seamless interchange of reduced data.
Brookhaven at SAS Useful discussion but venue not conducive to get work done
Grenoble May 2001 – “Aid”  “Action”. Importance of other issues discussed.
RAL May 2004 – Significantly expand beyond format and software.
NIST Oct 2007 – Working Groups created to achieve “action”
Oxford - SAS 2009 – Afternoon session presentations and discussion
Uppsala July 2012 – Small working meeting – significant progress on “action” part.
(Discussion at lunch of SAS 2012 in Sydney)
Tokai April 2015 – GISAS, NXcanSAS and agree to try for regular 3 year meetings
(Discussion at lunch at SAS 2015 in Berlin)
Berkeley, June 5-7, 2017.

Reproducibility and Reliability
Round Robin work
Glassy Carbon is now available as an SRM
Data formats work
1D format approved May 2009 (1.0) and 2013 (1.1)
nD ratified by NeXus Inter. Adv. Comm. End of 2016
IGOR working group resolved conflicts and was sunseted Apr 2015
New GISAS working group created Apr new direction

5. canSAS: Purpose and Goals
A self assembled (grass roots) group of SAS practitioners, users and facility people, who come together to:
Share and learn about emerging opportunities and new developments in the field and challenges that they pose.
Build new collaborations
Work co-operatively to improve the field for all by:
Helping to develop and disseminate best practices
Identifying emerging & problem areas and the needs associated with them
Improving the state of the art by identifying and providing solutions to the challenges
Fostering/Encouraging/Building common “tools” and “language” for SAS practitioners.

6. Role of canSAS workshops
Strong overlap with SAS meetings but fulfils different role
Presentations – looking beyond the “typical data set” from the “world’s best” instrument.
New directions and opportunities
But also -- challenges
Workshops aim to maximize interactions between participants with informal and in-depth discussions
Workshops provide an opportunity to find some realistic practical solutions that can be worked on NOW.
You can learn a lot more from failure than success

7. Each has block in the schedule.
canSAS IX : Meeting Orientation
Four topics
Each has block in the schedule.
Starts with series of talks highlighting cutting edge activities and current challenges.
Followed by 1.5 h to 2 h breakout discussion groups (~10/group)
Finish with 30 min plenary: summary and outcomes
Two topics today Monday
Reproducibility and Reliability
Information, Education and outreach

8. canSAS IX : Meeting Orientation and Goals
Monday Plan
Each topic has 3 20 min talks followed by 1.5 h breakout discussion
End of day 2 back to back plenary summary and outcomes
Breakouts
Need lead and/or rapporteur to lead/moderate discussion
Report to plenary ~ 3 “bullet point” style Highlights of discussion
USE WIKI to create live notes if possible.
Goals
Identify current challenges and problem areas.
Possibly identify concrete actions to address some problems.

9. canSAS IX : Reproducibility and Reliability
A Definition: To what extent can I be sure that the set of material property parameters extracted from my measurement represent the real parameters of my system? At the level that I need to know?
Some discussion starting points
How do analyzed results (final parameters extracted) from different techniques, including emerging techniques, compare?
Sources of uncertainties and resolution: how to identify and handle?
How to properly propagate and report uncertainties in co-refined data sets or in refinement constrained by results from other techniques?
Can we/should we develop new reference samples? How?
Aggregating/curating important information (e.g. instr. params. from SAS tools and scattering patterns from common standards)? How?
Best practices for handling of coherent/incoherent and inelastic scattering?
OTHER?....

10. canSAS IX : Information/Education/Outreach
Some discussion starting points
What is lacking – what is feasible?
Development and maintain sas portal? How? What priorities?
Aggregating existing instructional materials? How?
Creating new instructional media? What and how?
Generating scientific case studies? How?
NXcanSAS standard – How to disseminate? What is next?
OTHER? ….
