I have question about image registration. I have used ICBM_DTI_81 atlas for image registration in my case, control clinical research using linear transformation. After doing this i found good registration after i tested structures by the landmark option. Yet when i applied their ROI file (WMPM 90%) on my data, I found that the ROIs in the atlas are larger than the actual size of structures of my patients. Is there any solution for this?<br>
<br>
Or i should use other atlas for my registration<br>
<br>
Thanks<br>
Shaimaa<br>
