Has anyone changed the EEG electrodes locations in MNE (analyze or
browse_raw)? I found that two of my EEG electrodes are way off when I plot
them in matlab and wanted to know how I can solve this since the forward
model is affected by the electrode's locations.
I can make the changes in matlab when loading the files using the mne
toolbox but I want is to have the mne raw files with the correct
coordinates since all the other files will use them.
I don't know if anyone ever replied to this. Basically, the viewer in
mne_analyze uses a predescribed file, which you can generate (simply
look for "Creating a custom EEG layout" in the manual). I would be
very wary of putting in your own locations by hand (which you would
want to do in the matlab toolbox by editing the data in matlab and
writing back the raw files), unless you are quite sure about their
locations.
I would like to convert a 3D STC structure to a 2D matrix in Matlab which represents the flattened brain. It doesn't matter too much if I lose some areas of the brain, e.g. the medial wall, or the 2D map is slightly distorted. Apparently, MNE can visualise this, but it is not clear to me if I can export the 2D map to Matlab.
