[Eeglablist] Converting EEG Montage to Standard Montage

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]).

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?
