WebBesides the correction for multiple comparisons performed at the level of each resulting spatial map (cluster-wise topographic FDR correction; p < 0.05, q < 0.05; voxel-wise cluster-forming two-sided threshold p < 0.001 uncorrected), the statistical thresholds for the results were also corrected for the total number of seed-to-voxel analyses (p ... WebCluster-level inferences in voxel-based analyses. A standard second-level General Linear Model analysis of fMRI functional activation or fcMRI connectivity maps produces a single statistical parametric map, with one T- or F- value for each voxel in this map characterizing the effect of interest (e.g. difference in connectivity between two groups) at each location. how do new drugs get their names

WebIn versions 13e and below voxel-level FDR correction is done the old SPM5 way (at the level of voxels, not peaks), while cluster-level FDR correction is done the SPM8 way (at the level of clusters). In versions 13f and above we also added peak-level FDR-correction (the "SPM8 way", topological FDR, Chumbley et al.) and allow analyses to be ... 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.
