WebNote that refinement.cluster.homogeneous has been set to true.This option should always be specified when using a homogeneous cluster, since it makes FDR assume the cluster is homogeneous. If it is not specified there is a small chance FDR may fail to detect the homogeneity of the cluster, leading to suboptimal performance. WebSep 9, 2024 · While we focused on group differences at a corrected whole-brain node-wise significance level of pFDR<05 to minimize the risk of false-positives, ... The significance level for the seed-to-voxel analyses was set to an FDR-corrected cluster-threshold of p<05 at an initial voxel-wise height threshold of p<001 uncorrected. 3. Results.
