visualization & plotting

Emegs offers display & plotting utilities for a variety of data types and formats. Most elaborated however are the functions for the display of evoked potentials / evoked magnetic fields as curves (described under 2d-plotting) , and their projection onto a 3d headmodel surface (described under 3d-plotting).

For both 2d and 3d plot types, it is often of special to interest to plot statistical parameters, e.g. F- , T- or p-values. Emegs offers special features for displaying these values to quickly get an idea of the  plotted data, that are described here.

Besides these often used functions, emegs provides a number of specialized plotting tools (e.g. for creating plots in batchmode for multiple files and creating movie sequences).
