I'm having trouble with the normalization of some 3T epi images acquired with a 32 channel head coil. The normalization of the EPI images to the EPI template runs properly, but the resulting images are clearly not matching the template, particularly in the posterior brain. I haven't had problems like this with images acquired on different scanners. I have also tried coregistering the EPI images to the T1, normalizing the T1, and applying those parameters to the EPIs. That is more successful, but I'd still like to know what's going wrong with the EPI to EPI normalization, and what I can do to rectify the problems. The attached images show the "check reg" results with the "normalized" EPI and the template EPI images.
Thanks
