> According to:
> "I need generate a 3D head model from a resonance, then co register this head model with  10-20 electrode system to create my lead field matrix.
> this will work if you have the 3D position of the electrodes".
> I have only the patient MRIs, but no 3D positions of electrodes, just know that the system used in the acquisition is the 10-20 system with a number of fixed electrodes . Can i make my matrix Leadfield electrode using a template as standard_1020.elc?
yes, yet on the expense of accuracy. See for instance here: http://journal.frontiersin.org/Journal/10.3389/fnins.2014.00042/full
