Dear Sir/Madam,

I am a new fieldtrip user and want to apply the beamformer method in Fieldtrip for the MEG data from 4D/BTI system. Now I can get a individual subject MRI in analysis/spm format from CURRY software.

This is my code for create volume head model for the beamformer,

mri_nom = ft_read_mri(mrifile);

cfg = [];

[segmentedmri] = ft_volumesegment(cfg, mri_nom);

cfg = [];

cfg.method = 'singleshell';

vol = ft_prepare_headmodel(cfg, segmentedmri);

The vol and sensor locations were displayed and attached with here.

How can I co-register the vol with sensors based on headshpe file (hs_file) for computing lead field for next step?

Thanks a lot.

Best regards,
