Hi MRtrix Users,
I am wondering the tracking error with iFOD2.
I made one fiber bundle and simulated the DWI ( 60 gradient directions and b=1000).
The DWI was added Rician noise with High SNR.
The fODF was estimated and I qualified it and confirm it was correctly estimated.
SD_Streem algorithm could track the fiber properly, but iFOD2 could not generate proper fibers.
Does anyone have an idea?
Here is all the data I used.
The command is below.
dwi2response tax dwi.mif rf.txt dwi2fod csd dwi.mif rf.txt fod.mif tckgen -algorithm SD_STREAM fod.mif track_SD.tck -seed_image seed.mif -select 2000 tckgen -algorithm iFOD2 fod.mif track_iFOD2.tck -seed_image seed.mif -select 2000
The simulation fiber bundle is below.
The reconstruct fODF is below.
The result with SD_Streem is below.
The result with iFOD2 is below.
Seed region is below.
