Mismatch between coordinates of defined ROI and Matlab output

Hi everyone, I have the following problem: I tried to compute functional connectivity by using the 'Define ROI' button. As ROI I selected one of the Default ROIs (taken from Andrew-Hannas nodes of the DMN). This Region had the following coordinates: -6 52 2 (radius: 5). However, the following output in the Matlab command window does not fit these coordinates. See the following lines ... ' [...] Sphere ROI Center: 49 90 36 Radius: 5 Brain Size: 91 109 91 Voxel Size: 2 2 2 Contained Voxels: 81 [...]' Is there an explanation for this problem and how can I assess the coordinates that were truely used for computing functional connectivity? Thanks everyone in advance Jonas
