Hi,

I have followed the instructions in your website for constructing a
cortical surface sourcemodel with fieldtrip, freesurfer, and workbench and
constructed a sample sourcemodel for Subject01. The thing is, I want to
test some ideas for solving EEG inverse problem, but I do not know how to
calculate the leadfield using the aforementioned sourcemodel because I do
not have access to any headmodels and also I do not know how to do the
configurations correctly. I will appreciate it if you can guide me how to
do this.
Also, can I access any atlas parcellations (the voxel locations for
different regions in different Atlases) using the output of the
instructions in the website? (The link below is the instructions which I
have followed).

Thank you in advance for your help,
