That slicing does look interesting, but how do you get the whole view back? Oh, it looks like re-pressing x,y, &/or z enough times afterwards brings the view back, ok.
But I’ll have to see if that’s sufficiently useful, since moving a gyrus slightly aside as one could do with fingers or probe would seem to be more visually (& pseudo-tactilely) informative, but I’ll give the slicing a try. Thanks!
I did suspect there may not be any such tool to ‘move’ a gyrus to open a sulcus some, though I think you do have some deformation routines that could maybe be extended toward that purpose?
