Hi Sheraz,

Thanks for your suggestion! I am not familiar with SPM and brainstorm, would they allow to import bem files, scale them to fit the digitization data in a fiff file, and export them again as a bem? Or would I have to do the whole source estimation in the respective package?

Thanks!

Christian
