Dear freesurfer experts,
I have analyzed inter-group differences in cortical thickness using freesurfer 5.3.0 and QDEC. I have found one significiant cluster in the medialorbitofrontal region that is corrected for multiple comparisons using Monte Carlo simulation (p<0,05) and listed in the qdec output file "mc-z.abs.th13.abs.sig.cluster.summary". However, the cluster shown in the display window of Qdec is located both in the lateralorbitofrontal and the medialorbitofrontal region. Why is the lateralorbitofrontal region not mentioned in the file "mc-z.abs.th13.abs.sig.cluster.summary"?
I have attached the contents of the output file and a screenshot of the display window of QDEC after the Monte Carlo simulation.
Thank you in advance for your help.

It may cover both, but the peak can only be in one, and it is the peak that is reported.
