Hi Greg you could threshold then look at Hausdorff distance of the blobs. Or you could smooth before computing correlation as that will take spatial stuff into account. Or if you have a patch that you want to cross-correlate against the rest of the surface you could do it on the sphere, althou

[Freesurfer] cortical surface pattern matching

2016-06-20 Thread GREGORY R KIRK
Hi, has anyone created functionality to compare the spatial correlation/similarity of two patterns in the form of cortical surface overlays. What I am looking at is a have scalar at every point on the cortical surface. obviously this is just a list of vertices with a scalar value associated
