I was curious if there was an updated tutorial or go by for labelling seeg? With 20 or so 10 contact depths, using the 3 slice method seems very difficult. I have been using bioimagesuite to label these, and it can make a version of a text file, but it is not importable. I am happy to send a text file, raw text file (*.mgrid format but its really just text) and the vtk it makes if that would help. If there is a way in brainstorm or brainsuite to do this in 3D using the thresholded CT or MRI, I would love that.
