Hi, We have been trying to replicate the manual cortical surface-volume tracing method for the enthorinal cortex described in Feczko et al. (2009) and Dickerson et al. (2009). In this method, points selected on the coronal MRI slices (in the tkmedit) are matched to points along the surface of the reconstructed cortical surface model (in tksurfer). These points are used to define anatomical landmarks and they serve as connection points in the surface volume for tracing. We are running into problems with loading multiple control points on the surface volume. That is, when we place control points on the MRI data and then Go To Saved Point in the surface volume then we only get a single most recent placed point while the other points specified in the MRI slice are "lost". Is there a way we can load all these points simultaneously on the surface so that we can demarcate borders as described in these papers? Thanks -Gail Musen
Hi Gail,
you probably want to draw labels and use them to go from volume to surface instead of using save point/goto point (which only does a single point)
