Dear Freesurfer experts,

I hope you can help me with the following questions:

1. What is the best way to know the MNI coordinates to which a vertex

of a surface corresponds?

I think freeview will display the mni305 coords

2. I have projected the surfaces of the subjects onto the average

subject from this dataset. Can I know the MNI coordinates corresponding to a vertex of the average subject of my dataset? Or do I need to project it onto the fsaverage to know the correspondence to de MNI space?

An average subject is always in mni305

3. I know that the average surface is constructed by computing the

MNI305 coordinate at each vertex, But how can I obtain the MNI152 coordinates (instead of MNI305) to which a vertex corresponds? (if it is possible).

See case 8 in website above

Thank you very much in advance.

Best regards, Marina
