Matt,
I tried registering my FA map to the T1 scan using both 6 and 12 Dof. The
resulting images look identical, with exception of a few voxels. The
registered FA to T1 image is stretched out beyond the borders of the
original T1 image. Is there anything you could suggest to improve the
registration?
You mentioned that I could try to use FNIRT for this registration. I tried
FNIRT a while back, but the results were similar and I was advised against
using FNIRT for this registration since FNIRT was not written for
registration of images with different contrast. Has that changed recently?
Thank you,
Anastasia
