collayers.merge

named list, the values must be vectors, matrices or arrays of color strings (as produced by <code><a rd-options="grDevices" href="/link/rgb?package=fsbrain&version=0.4.3&to=grDevices" data-mini-rdoc="grDevices::rgb">rgb</a></code>. The names are freeform and do not really matter. All values must have the same length.

collayers

a single color string or `NULL`. If a color string, this color will be used as a final opaque background layer to ensure that the returned colors are all opaque. Pass `NULL` to skip this, which may result in a return value that contains non-opaque color values.

opaque_background

Merge several color layers into one based on their transparency and alpha blending. In the final result, the lower layers are visible through the transparent or `NA` parts (if any) of the upper layers.

Provides high-level access to neuroimaging data from standard software packages like 'FreeSurfer' <http://freesurfer.net/> on the level of subjects and groups. Load morphometry data, surfaces and brain parcellations based on atlases. Mask data using labels, load data for specific atlas regions only, and visualize data and statistical results directly in 'R'.
