Please is there a way to set the number of dipoles to be equal to the number of channnels (let’s say number of channels that are in the mne.channels.make_standard_montage(‘standard_1020’))?
Few months ago I asked about how to set the number of dipoles and this link was provided setting up number of dipoles. After playing with things, I used the
With so little dipoles, you are no longer performing a “distributed source estimate” as techniques like MNE assume. Can you give us a little more information of what you study is and what you are trying to achieve?
I am trying to understand and study dipole locations that match the locations of electrodes of a standard montage. I want to know if by chance I could get specific dipole locations that match lets say the 10-20 electrode position system.
That’s why I asked if the dipoles could be reduced to suit the number of electrodes.
It sounds like you would like to see how each dipole influences each specific electrode. This is something that you will not get with subsampling the source space to 20 dipoles.
What you can do, however, is calculate the sensitivity maps from the forward operator. These sensitivity maps can show, for each electrode, their sensitivity to activity from the different sources.
