Dear HCP users, Recently, I have tried to calculate the zero-order correlation between some brainstem ROIs and the cortical vertices. Looking at the mean subjects' correlation map, the connectivity pattern totally makes sense. Even after doing the statistical testing (using permutation based on maximum t-statistics) the significant correlated clusters are located in the expected areas. However, the magnitude of the correlation coefficients are very small (in the order of 0.05 for the peak vertices in the mean map). I have also done the volume-based voxel-wise analysis for the same brainstem ROIs and I had similar findings there. Is there any explanation for such small r-values even though the significant correlations seem to be meaningful?
Thank you all, Amin _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
