Dear Hedok,
Thank you for your reply. I have tried the 3% noise and 20% intensity
nonuniformity T1w Brainweb image and obtained similar results. I used
3dSkullStrip to remove the skull first and then applied FAST with default
parameters. Yet, I am still getting very high misclassifcation rate and the
visual overlap is also quite poor.
Please let me know if you have any suggestions. Thank you so much.
Best Regards,
On Tsang
PS. I am using FAST version 3.53 and the latest version of AFNI
