volume.clusters.colormap: Compute the shared colormap of the cluster shells.

In fsbrain: Managing and Visualizing Brain Surface Data

Compute the shared colormap of the cluster shells.

Description

All shells of both signs share one colormap, so that the color of a shell is exactly the color that the colorbar shows for its iso-level. A symmetric range which covers all iso-levels is used unless the user requested a range via the 'range' entry of makecmap_options.

Usage

volume.clusters.colormap(makecmap_options, levels, max_abs = max(abs(levels)))

Arguments

makecmap_options	named list, the colormap options, see makecmap.
levels	numerical vector of iso-levels.
max_abs	single positive number, the absolute value of the most extreme value that the colormap has to cover, i.e., half of the range of the colormap. Defaults to the highest absolute iso-level.

Value

named list with the entries 'map' (the squash colormap), 'colors' (a color per entry of levels), 'range' (the range of the colormap) and 'options' (makecmap_options, including the range, for the colorbar metadata of the meshes).
