[FieldTrip] Convert fieldtrip beamformers to SPM

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

Dear Sabrina,

I am not sure why your conversion to nifti does not work, but if you follow the recipe that is described in http://www.fieldtriptoolbox.org/tutorial/beamformer, in particular by using ft_sourceinterpolate to create a volumetric image of ther source-reconstructed activity, followed by an optional volumetric normalisation (using ft_volumenormalise), it should be relatively straightforward to save this to a nifti file.

Best wishes,

Jan-Mathijs

Dear fieldtrip community,

I analysed my EEG data in fieldtrip and calculated beamformers. I would like to compare these source data with my fMRI sources and therefore do both statistical testings in SPM. But how can I export my beamformer data to SPM? Converting them with spm_ eeg _ ft2spm does not work with beamformer data.
I also tried ft_volumewrite to convert the beamformer results to nifti, but without succes.

Thanks in advance,
Sabrina
