Dear MNE community,
I tested if my data source space data were significantly different between 2 groups of subjects by performing a cluster-level permutation test across space and time, as in:
As a result, I got a “significant cluster” with the coordinates of maxima: -18.4, -41, 47.7. After searching for these coordinates in a human brain atlas, I realized they’re outside of the MNI space and it’s probably a white matter tract.
I’m aware of the issues about localizing significant activity in time and space after a permutation test, but I ask myself if the fact that my results are outside of the MNI space are an indication that my source localization was not accurate? Or is it something to be expected?
I would really appreciate any contributions,
