[FieldTrip] Topoplot layout

[Schoffelen, J.M. (Jan Mathijs)]

Dear Vladimir,

I am a bit surprised that the sensors are so far away from the rim. I suspect that your attached figures are created from an attempt to layout creation from the sensors’ 3D positions, rather than from a pre-cooked layout file.


If I use cfg.layout = ‘CTF275.lay’, load the layout lay=ft_prepare_layout(cfg), and plot it ft_plot_layout(lay,’box’,’off’,’label’,’off’), it doesn’t look too bad. It gives the panel on the left in the attached screenshot.

These days, however, we recommend using ‘CTF275_helmet.mat’ as cfg.layout. This gives the right panel in the attached screenshot.

If I were you, I’d go for the helmet layout.

Best wishes,
JM

Dear all,

I'm trying to use topoplotER for CTF data and it looks like the sensors do not reach the edges of the scalp and large parts of the map are interpolated. This happens both with the sensors and with default layout. Not sure if it was like that before but is it normal? Is there an option to do a plot like in EEGLAB where some of it is outside the head outline or do something else to fix this?

Thanks,

Vladimir
