[Mne_analysis] Plotting topographies for MEG sensors

[Denis-Alexander Engemann]

Hi Diana,

could you share the script you were using?
Did you make sure that you were using the correct layout. In case your MEG-system isn't a Neuromag 'vectorview-all' will not work. The plotting function assumes that channel names of raw match the layout names.
So you could compare raw.ch_names with layout.names.

Hope this helps.

Denis

Thanks both, unfortunately Im now getting the black image box with my title but no actual plots when I use the plot_topo function even though I can see the evoked object when I use plot_evoked.

Hi Diana,

this looks like the mne-python interface. Which version do you currently use?
Recently there was an API change recently. Here is a script that demonstrates how to do it with the current developmental version.

I am trying to plot meg evoked data using vector-view layouts but keep getting the error message that the .lout files cannot be found when I call this line

layout = Layout('Vectorview-all')

Any obvious reasons why I might be having trouble?

Many thanks
