Consider for example how the North pole is distorted on a map of the world. However, projecting 3D sensor positions to a 2D plane always incurs distortion, especially at the edges where the surface is “bending” away from view. The geometrically most accurate layout representation can be obtained from a 3D representation of the sensor positions as a grad/elec/opto structure. a photo or drawing of the sensor positions.the position of the sensor positions in 3D space.The layout results from ft_prepare_layout and can be constructed from The layout is a schematic 2D representation for displaying the data on the computer screen or in print on paper. Many of the FieldTrip plotting functions use a 2D layout of the channels for plotting. outline = optional cell - array with line segments that represent the head, nose, ears, sulci or other anatomical features Constructing a layout mask = optional cell - array with line segments that determine the area for topographic interpolation layout. height = Nx1 vector with the height of each box for multiplotting layout. ![]() ![]() width = Nx1 vector with the width of each box for multiplotting layout. label = Nx1 cell - array with the channel labels layout. pos = Nx2 matrix with the position where each channel should be plotted layout.
