tfce-corrected table with a list of peaks that covers the whole brain
Dears developers, 
I'm working on a meta-analysis of gyrification differences between patient and control groups. The analysis is mostly an SBM IBMA but I included coordinates for a few studies because the authors did not provide images. When I successfully run my analysis and open the tfce-corrected table, it brings me to a webpage with 1 significant cluster showing hypogyrifiation in the patients group. However, when I'm clicking on "show additional cluster information", I get a really long list of peaks with p=0.000999987. There are so many peaks that I think they cover the whole brain!

Do you know what is going on?

The preprocessing parameters I used were: 
- Modality: VBM - gray matter
- Correlation template: gray matter
- Anisotropy: 1
- Isotropic FWHM: 20
- Mask: freesurfer
- Voxel Size: 2

I'm attaching you the tfce-corrected table.

Many thanks for your help, 
Layla
