Hi Keith,
this is inevitable when sampling from the volume onto the surface,
particularly if the volume maps are blurry. Then a single volume blob will
intersect e.g. two banks of a sulcus and show up as two distinct blobs.
cheers,

Hi FS experts,
I am trying to display a large set of peaks on an inflated brain to
illustrate the spread of the peaks over a gyrus & sulcus, similar to
what might be done in a meta-analysis. Is there an easy way to do this?
I tried generating a binary mask in 3D (in MNI space) and then
converting that to a .w file using mri_vol2surf but some of the peaks
seem to be lost and the peaks that do appear, are splodges rather than a
neat circle/ellipse/whatever, which makes it look like an activation map.
Thanks in advance!
Keith
