Dear MNE users,

I have been using \*mne.viz.plot\_topomap\* to plot topography with the \*pos \*  
argument coming from \*read\_montage \*which was noticed to be deprecated in  
v0.20. The following is an example:

\*pos = mne.channels.read\_montage('biosemi32').get\_pos2d()[0:32,0:2]\*  
\*plot\_topomap(x, pos)\*

I have learnt that we shall use \*make\_standard\_montage('biosemi32') \*now  
but I havent found a function to get the corresponding electrode positions  
from the returned \*DigMontage \*instance to serve as the input of \*  
mne.viz.plot\_topomap. \*Does anyone have ideas?

Thank you so much.  
Best regards,  
Matthew

hi,

i don't think we have a public function to do this but you can use:

m = mne.channels.make\_standard\_montage('biosemi32')  
m.\_get\_ch\_pos()

note that this is using a private function
