Hello,
I am trying to use IFOD2 with GQI. I’ve calculated the L=8 SH coeffs for GQI, but GQI as a whole produces FODs orders of magnitude smaller than CSD or MSMT-CSD. I can normalize these coefficients where the max value of the FOD in each voxel is = 1, but that would pretty significantly alter / diminish voxel-voxel differences in FA and related metrics, so I am hesitant to do this.
My question is this: when using tckgen, how should I calculate the appropriate cutoff value, as to not have tckgen follow spurious peaks? Does anyone have any suggestions of experience with this?
Thanks in advance!!
Hank
