Accuracy for REST in the presence of noise in the electrode positions. The graph shows descriptive statistics about the increase of global relative error obtained by systematic shifts either corrected (SSc) or not (SSu) and random shifts (RS) across 100 dipoles oriented along the x-, y- and z-axis, with noise level equal to 1, 2, 4 and 8 mm. This analysis was conducted for 10 different realizations, using a three-layer BEM and an EEG montage with 256 channels.
