.gii overview issue between CAT12 and surfice

[iPsych]

Describe the bug
The CAT12 extension provides .gii for 'save cluster' function.

Although Surfice can overlay the .gii files automatically generated during statistical analysis (i.e. beta_0001.gii),
The clusterfile cause below error with proper vertex-numbered template (mesh.central.freesurfer.gii).

GIFTI overlay has a different number of vertices than the background mesh (1 vs 64984)

I tested with multiple dataset, but the results are always same.
