ICA SPM results: seed-to-voxel vs. voxel-to-voxel/spatial summary; what is difference?
I notice that the SPM maps from voxel-to-voxel results explorer and
from ICA spatial summary are identical. After back-projecting
the ICA maps by adding as new ROI, the resulting seed-to-voxel SPM
maps are very different for the same
between-subject/between-condition contrasts.
It is still unclear -
1) what is happening during preprocessing to the ICA maps that accounts for these differences
2) which approach is valid for assessing brain-behavior relationships?
Many thanks in advance,
Patrick
