measurements of distance of electrode from center of nucleus

[Nik Haliasos]

Hi to the group,

if i wanted to do measurements of distance of electrode contacts from let us say the center of the STN nucleus or a position defined by myself on the scan would that be feasible?

thank you
Nik

Hi Nik,

sure, the contacts are stored in ea_reconstruction.mat -> reco.mni.coords_mm (for template space) and reco.native.coords_mm (for native space).
You can easily define a point in space and e.g. calculate distance with the pdist function of Matlab.

Best, Andy

Hi Andy,

To follow up on Nik’s question, how would you go about obtaining the coordinates of a specific structure (ie. STN, Red Nucleus, etc…)? I can easily view the surface coordinates of any structure using the data cursor on but cannot seem to obtain the coordinates at the center.

Thank you,
Anthony
