Subject: QDEC versus Terminal annotation
To: Freesurfer support list <freesurfer@nmr.mgh.harvard.edu>


Hi,

I am comparing cortical thickness measures between controls and patients. I displayed the results in qdec. I found that cluster is showing significant difference in thickness between controls and patients (controls having more thickness than patients).

In terminal, its showing output as:

ClusterNo  Max   VtxMax  Size(mm2)   TalX   TalY   TalZ NVtxs Annotation

    1    2.6021     130    1285.86    11.5  -89.5   21.1 1764  superiorparietal

I am not an expert in anatomy but when looking at the cluster in qdec (please find it attached), it seems like the cluster is not superior parietal as shown in terminal and even TAL coordinates are not matching with standard superior parietal lobe coordinates. When I click on find cluster in qdec, shouldn't cursor on that cluster show the same area shown in terminal?

Could you please share your thoughts on this, why the area displayed in terminal window is not matching with the one shown in qdec ?

Thanks.
