Notes:

1. Discuss immediate action items from the last meeting.
   • Ahmet has been working on the segmentation of oks001 MCL. He was able to identify sueprficial and deep layers of the MCL and noted that generation of the geometry requires some art. He committed a rough segmentation in the repository.
   • Ahmet also learned a few tricks in Slicer that can facilitate segmentation.
     • Different MRIs can be displayed in different windows, e.g. those that are ligament specific and cartilage specific. When linked, Slicer uses interpolation for coupled viewing of the image sets that are already spatially aligned. This feature may be useful to generate images of zoomed-in regions to see how a given tissue type looks like in different imaging sequences. This feature also helps segmentation, i.e. one can use one image set as the master volume but segment in the other allowing high resolution segmentation volume from images with lower resolution.
     • Ahmet provided some tips using manual segmentation tools. The pencil works to draw straight lines, e.g. by simply clicking. The eraser changes the behaviour of the tool, e.g. brush or pencil, to erase rather than draw.
     • Ahmet will document the tips for the use of Slicer in image segmentation specifications.
2. Continue evaluation of drafts for data manuscripts.
