Hi all,
thank you for your fast reply! Yes, I found this post mne.channels.read_custom_montage('128+8locs.xyz'): ValueError: could not convert string to float: - #15 by richard and figured it has to do something with the scaling.
I tried the division by 1000 and it resulted in a still slightly off montage (see attached)
My montage file also contains columns with radius, do you think I should use that in any way?
Thank you
Anna
