DTI Meeting Minutes | October 11, 2006


Present: Doug, Kate, Marc, Sylvain, Jenny, Martha, Gordon, Toshiro, CF, Katharina, Gudrun, Marek


Review of last week

  1. Fornix tractography
    • Sylvain spent time with Doug and Kate this week to figure out the 'bad' fornix cases, but they weren't able to remedy the problem cases. Lowering the anisotropy threshold does not help.
    • Sylvain will email case to Gordon so that he can take a closer look
  2. Cutting tracts
    • Marc wrote a Matlab script to read in tracts (.vtk) and cut along planar labelmap ROIs. Doug will show the output of the script at the next meeting.


OR function in DTMRI

  • Sylvain noted that there is no 'OR' function when selecting tracts in DTMRI (while you can use 'AND' and 'NOT'). He will talk to Raul about adding this option into the module.


NAMIC Meeting next week

  • Next tuesday there will be a meeting between Cores 1 and 3. Sylvain and Marc will be demonstrating ongoing work.
