How do I export the position of electrodes in MRI coordinate after registration?

1

It seems that after registration, I can only export the SCS coordinate of the electrodes. I can only view the MRI coordinates from the MRI viewer. Is there anyway I can export the MRI coordinates of the electrodes directly?

Hello,

I’m sorry for the response delay, I’ve just realized no one addressed your question.

  1. Get the positions of the electrodes in SCS coordinates:
    http://neuroimage.usc.edu/brainstorm/Tutorials/ChannelFile#On_the_hard_drive
  2. Then put them all in the same matrix: P = [ChannelMat.Channel.Loc];
  3. Convert from SCS to MRI coordinates: http://neuroimage.usc.edu/brainstorm/CoordinateSystems#Converting_between_coordinate_systems
