I am trying to use ICA to clean EOG and ECG artifacts of neuromag data.
I am running ft_topoplotIC(cfg, comp), where 'comp' is the output of
I get the following error message:
??? Error using ==> surf at 74
X, Y, Z, and C cannot be complex.
Error in ==> ft_plot_topo at 184
h = surf(Xi-deltax/2,Yi-deltay/2,zeros(size(Zi)), Zi, 'EdgeColor',
'none', 'FaceColor', shading);
Error in ==> ft_topoplotER at 753
Error in ==> ft_topoplotIC at 116
The complex variable is 'Zi', which is taken from 'comp'. I can modify
the function to take the real part of the variable (or the absolute
value), but I am not sure if this would be the correct thing to do. In
case this is a bug, I thought I should report it. Any comments?
Thanks for your help,
