[Eeglablist] Converting EEG Montage to Standard Montage

Hi James, 

Thanks for your email! 

So, should the electrode labels be the same in the original EEG file and the
new coordinates? Could you please elaborate more how should I use the
plug-in?

Best

Iman

Hi Iman, 

 

I have an EEGLAB extension "Interpmont" that may help. It can be downloaded
from the public github repository here.
<https://github.com/jadesjardins/interpmont> 

 

"EEGLAB extension for interpolating recording locations. Utilities include
changing current locations to fit a model surface (warplocs), Interpolating
current data to locations in a coordinate file (interpmont) and
re-referencing to the average interpolated site from a coordinate file
(interpref)."

 

Once you have the extension folder extracted into the EEGLAB plugins folder
use " Tools > Interpolate to coordinate file > interpolate the data to sites
in a coordinate file". In the GUI select an EEGLAB recognized coordinate
file and then in the "Optional inputs" edit box enter <'manual','on'> (this
will allow you to coregister your loaded data set chanlocs coordinates to
the surface of the new coordinate file [if they are not already on the same
surface]).

Hi EEGLABers, 

 

I want to transform my current electrodes' montage (128ch - bad electrodes)
for each individual subject to a standard montages ( like 81 channels ) like
what I can do it in BESA to make all of the electrode locations standardized
for group comparison in ELECTRODE SPACE NOT SOURCE SPACE. Is there any
function /plug-in to do it?

Best

Iman
