Minutes

1. updates of action items and items in progress
   • From canSAS VI
     • SAS Portal
       • Paul has investigated finding a student and has identified funds.
     • 1D and 2D data formats
       • Pete - Nexus code camp has lead to a SAS format definition that he will post the URL to so we can review it and comment.
       • http://trac.nexusformat.org/definitions/browser/trunk/applications/NXsas.nxdl.xml defines minimum set of tags/info for small angle scattering. NB - this is for monochromatic scattering only : TOF and GI not considered.
       • Timeline for NXDL? (AJJ) - PRJ says approx. 6 months.
       • AJJ - Make sure we are really talking about reduced data. What is needed to allow the NXsas to be used for TOF data?
       • PRJ/SK - Have added namespaces to handle wavelength dependent transmissions etc.
       • RH/AR - Handling different q-space maps / detector geometries?
       • CF - noting meeting : http://www.esrf.eu/events/conferences/hdf5/hdf5/
       • PRJ - Action: Review of NXsas format?
       • Action: Get some North American people to CF's meeting.
       • AR to PRJ - any planned tools to read NXsas. Answer - Ideas: Translation app or browser/plotting app. Best answer would be strong bindings for various languages.
       • Watch and wait on nexus before leaping in to 2D.
       • PRJ - Licensing. Need debate within working group.
       • AR - Update on 1D usage? AR wrote to ILL (Andrew Harrison) regarding use of format and has had no response. AJJ - NCNR will support in next release. No other updates.
       • CF suggested that AR goes to visit new SAS beamline.
     • Standards - Extension of mailing list archives
     • IGOR develper's progress?
       • AJJ Talked with Jan Ilavsky.
       • AJJ asked KL for his current code to test compatibility.
