template matching dimensions mismatch using data from CTF machine

Hey,
I'm trying to use template matching (mne.preprocessing.corrmap) to remove blinks artifacts.
The only problem is that the data I'm analyzing was collected using a CTF machine, and all my data I can use for template matching was collected using an Electa machine.
When trying to call the corrmap function, I'm getting an error from the mne.utils.compute_corr function because of dimensions mismatch (which makes sense, my reference has 305 sensors while the CTF data has only 147)

Any ideas?
Thanks,
Noam

you should pick a reference for a CTF system.

Thanks Alex!
Unfortunately, I don't have EEG data for that. Should I use a frontal MEG sensor instead?

Thanks,

for the template you need a full topography that you identified as an
EOG topography.
this is AFAIK a manual step
