Hello experts,
I want to extract mni coordinates of the destrieux atlas seeds (x, y and z). How can I do it? Can you help me?
Regards,
Jennifer

Hi Jennifer,

You can get the vertex coordinates of the surface (in SCS coordinates) from the cortex surface:

You can get the index of the seeds of the various scouts in the atlas of interest from the same cortex surface:

Then you can convert from SCS to MNI coordinate systems with cs_convert:
