sourceanalysis.m on EEG data

[Brian Roach]

I am working through this tutorial on the web:

http://www2.ru.nl/fcdonders/fieldtrip/doku.php?%20id=fieldtrip:documentation:tutorial:beamformer#plot_the_result

I am wondering, do you only need to use MRIviewer to construct a forward
model for MEG data (and not for EEG data)?  What kind of software do I need
to use to construct an .hdm file for EEG data?

thanks!
