Dear all,
for a study I want to compare different voxel sizes of EPI sequences with the same paradigm. The one sequence was measured whole brain, while with a different one, only half brain was measured with smaller voxel size (same TR). Normalization of the half brain to whole brain EPI template looks just fine (without using co-registration to the structural data) for all subjects. At second level, as main effect of acquisition scheme, I find strong activation in my region of interest. Can I compare these two different acquisition schemes and how can I be sure that normalization of the half brain is correct (using SPM8)?
Thank you,
Roman
