I think the coordinate circled in the picture is the exact coordinate of the vertex, also in surface ras. The coordinate under "SurfaceRAS" is the coordinate of the current cursor location in surface ras. The slight difference is because the cursor is not exactly on the vertex, but close enough so that the vertex number is shown.

Hi there
Doug can you please confirm? Bruce said you would be the best to answer and I've got revisions that are due. Please see the image attached. In my manuscript I report the x,y,z next to the vertex number in Freeview for MNI coordinates (MNI305) of that vertex. These only different very slightly from the RAS and SurfaceRAS coordinates above the vertex number in the panel but I'd like confirmation I am reporting the correct x.y,z.

Hi there
This might be a very silly question but I actually cannot find the answer in the email archive:
Assuming I have loaded a label onto fsaverage in Freeview and want to get the MNI305 coordinate of that labelled vertex, am I simply using the x,y,z in brackets in the panel? I attach a photo of what I mean.
