[Freesurfer] tkmedit coronal view - y coordinate issue

Hi,

In FreeSurfer 5.3, when I click around in a coronal view slice, the Talairach y coordinate changes (in both the cursor column and the mouse column). This doesn’t make sense - it’s the same coronal slice, so shouldn’t anywhere on that same plane still have the same y coordinate? When I take a screenshot of the brain map and report the y coordinate, is there a standardized procedure for where in the slice I should click to take that coordinate to report?

Thanks, Stephanie
