You can tell from the sign of the "VtxMax" column that indicates the maximum in the cluster. If you used a signed test (pos or neg), then they will all have the given sign. If you used an unsigned test (abs), then they may have different signs.

External Email - Use Caution
Dear FreeSurfer experts,
I am running whole-brain based group comparisons of cortical measures between a patient group and a control group using glm-fit and Monte-Carlo correction for multiple comparisons.
It works fine but I am not sure where to find information on which group has more or less volume, for example, in a significant cluster.
I use the xxx.sig.cluster.summary files which give me something like this:
ClusterNo
Max
VtxMax
Size(mm^2)
MNIX
MNIY
MNIZ
CWP
CWPLow
CWPHi
NVtxs

Is the direction hidden somewhere or in another file? Do I have to run additional commands to get to the information?
Thank you so much for any advice!
