Hello SPM experts,
I am using the "PET & VBM" module in SPM8.
In the results graphic and after selecting "whole brain" results, if there is a cluster large enough to pass significance after FWE and/or FDR correction then the cluster size is given at the bottom left of the Statistics result table under the headings...
FWEc: "number of voxels" and FDRc: "number of voxels"
What is the FWE and FDR cluster level corrected p value that applies to this test? (I presume this is a default setting within SPM)
Can the FWE and FDR cluster level corrected p threshold be adjusted, hopefully using the GUI or by changing the programming code?
Thanks in advance,
Kevin London
