Discussion, future planning

• • 11:25 CF Westin to kick-off discussion of Tractography results with summarizing ideas. Meeting Notes

12:00pm: Lunch

• • 1:00- 1:20pm Presentation of current status of Slicer 3 DTI infrastructure (Alex Yarmarkovich)Slicer3 DTI status
  • 1:20-1:30pm Dan Marcus to gather requirements to post this dataset for consideration of whether this is an XNATophilic project
  • 1:30- 3:00pm Continue discussion of Tractography results with focus on:
    • Data formats and coordinate system requirements/guidelines/recommendations
    • Quality control methods and implementation
    • ROIs: what works, what doesn't, what to do?
    • Registration &/or resampling to support visit 1- visit 2 analysis and group analysis
    • Freesurfer to B0 transform for white matter mask
    • Quantification of registration error and its propagation forward and impact on final results
    • Plans for data sharing curation and timeline (integration with XNAT project, should we make plans for a NAMIC sponsored MICCAI event: Tractography Grand Challenge e.g. the one done last year for segmentation? See http://mbi.dkfz-heidelberg.de/grand-challenge2007/)
    • Outcome metrics and how to best frame scientific questions for this project, steps towards manuscript preparation, milestones for spring 2008 and for Programming Week in June

3pm: coffee break

• 3-4PM Batchmake break-out session
  • 4:00pm Guido to lead discussion of "NAMIC software infrastructure for DWI analysis" to clarify what the community expects from a powerful NAMIC DWI Analysis toolkit and identify areas of high priority development, keeping in mind the work already done by Alex (see 1 PM talk).
    • Identify and agree upon essential processing steps (pipeline) necessary for clinical DTI studies
    • Identify Core-1 modules and methods that are a) recently integrated, b) ready to be integrated, c) in development
    • Integrate with other on-going efforts
