 In this case, we are using the tutorial data and the standard BEM model described in the previous sections. The BEM head model mesh was extracted from the average MRI used for plotting, so the alignment is perfect. When using participants' MRI and transformed them to MNI space (for example, using SPM), this allows checking the alignment between the MRI and the head model. 
 
-It is also possible to compute extract 3-D meshes from your participants' MRI and use them to create head models as described in this [Fieldtrip tutorial](http://www.fieldtriptoolbox.org/workshop/baci2017/forwardproblem/). If you have a custom head model, use the dropdown menu *Custom model files from other template or individual subject* in the head model settings. A custom head model for MEG is also possible and described in the next section of the tutorial.
