[FieldTrip] Using inverse kernel with EEG to calculate sources

[Schoffelen, J.M. (Jan Mathijs)]

Hi Valentina,

Could you please check

https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1002202

and ask your question in a more constructive way?

Also, I think that there is ample documentation on the fieldtrip website that should get you started. With respect to your question pertaining to ‘managing cell files’, please refer to the basic matlab documentation.

Also, please note that there are about 1500 e-mail addresses registered to this list, so in general I think it is not a good idea to keep reposting the same e-mail, even if you are very eager to obtain an answer.


Best wishes,
Jan-Mathijs

Oggetto: I:Using inverse kernel with EEG to calculate sources

Good morning, sir,
I'm Valentina, I calculated the sources of the fem model through ft_sourceanalysis with the eloreta method. I would like to put the opition to calculate the inverse kernel. At the moment I have written these parameters for the cfg
cfg.keepfilter='yes';
cfg.keepmom='yes';
cfg.method = 'eloreta';
cfg.headmodel = headmodel_fem_eeg_tr;
cfg.elec=elec;
cfg.grid=sourcemodel_fem;

keepmom what does it correspond to?
and in struct source.avg.ori what does it mean?
also how do I manage cell files {}('mom'',filter','ori')?

Thank you very for the help
