we're answering on behalf of Karl Friston and the SPM-authors.
Yes, there are plans to incorporate source modelling routines for
EEG/MEG data into SPM and enable one to do a multimodal data analysis.
The general idea is to use the framework of SPM and some extensions to
it to facilitate the analysis of EEG/MEG data. This builds upon the
distributed source localization approach developed by Christophe
Phillips. Some part of his effort could be seen at the 5th and 6th HBM
conference (e.g. http://www.apnet.com/www/journal/hbm2000/6207.html).
The task of making SPM work for modelled EEG/MEG sources will be
undertaken by Stefan Kiebel.
The next step will then be to combine the fMRI/PET/SPECT and EEG/MEG
analysis in such a way that an integrated analysis of these modalities
is possible in the unified framework of SPM.
However, as you can see from this rather brief description of our aims,
we are still at an early stage. We are currently working on it, but we
cannot specify a time frame yet. Any important information with respect
to some progress in this project will of course be sent to the
SPM-mailbase to keep you updated.
Christophe and Stefan
