Depending on whether you want to use EEG or MEG, and depending on what kind of method for computing the volume conduction model you want to use, there are different functions that construct "vol", i.e. the volume conduction model. </div><div><br></div><div>I just started to work on improving the documentation for head modeling and am also planning on cleaning up and renaming the functions. Here is a short summary corresponding to the current implementation:</div><div><br></div><div>for EEG there are</div><div><div> ft_prepare_bemmodel.m</div><div> ft_prepare_concentricspheres.m</div><div><br></div><div> and for MEG there are</div><div> ft_prepare_localspheres.m</div><div> ft_prepare_singleshell.m</div><div><br></div><div>Please look at the help of these functions.
