Brian,
Thank you for the fast reply.
What do you think of the following pipeline:
- $first_flirt on T1
- $run_first on T1
-Apply the inverse im1_to_std_sub.mat to the output_image and mask that to
the mfast output. Then use fslmaths to extract volume values....would that
give a better registration and segmentation or that's an incorrect
pipeline?
