Hi Bruce,
Thanks. Is it statistically sound to use e.g offset 1? My between-group results are not FDR corrected at offset 0, but if I change the offset to 1 results will be larger in size and FDR corrected! Any pitfalls with that?
Cheers Hamza

Hi Hamza
offset is the zero point of the colorscale. Usualy it is 0 so that atuff that is <0 is displayed in blue/cyan and stuff that is >0 in yellow/red

Dear Freesurfers and experts
Can any one please tell me what the offset box next to the max. box (under Threshold) in QDEC GUI is for? When I change from e.g 0 to 1 or higher I get larger significant clusters. How and when is this feature used?
I also notice this very question is on the archive list but not answered. Here is the quote "Hi Bruce,
I'm referring to "offset" in qdec/Display threshold line, near Min/Mid/Max. For example, I'm noting that if set +1 as offset the red statistical area is mor e larger. Stefano"
Thanks
Hamza
