<p>Dear Sir/Madam,</p>
<p> </p>
<p>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.
</p>
<p> </p>
<p>This is my code for create volume head model for the beamformer,</p>
<p> </p>
<font size="2" face="Courier New"><font size="2" face="Courier New">
<p>mri_nom = ft_read_mri(mrifile);</p>
<p> </p>
<p></p>
<p>cfg = [];</p>
<p>[segmentedmri] = ft_volumesegment(cfg, mri_nom);</p>
<p> </p>
<p></p>
<p></p>
<p>cfg = [];</p>
<p>cfg.method = </font></font><font color="#a020f0" size="2" face="Courier New"><font color="#a020f0" size="2" face="Courier New"><font color="#a020f0" size="2" face="Courier New">'singleshell'</font></font></font><font size="2" face="Courier New"><font size="2" face="Courier New">;</p>
<p>vol = ft_prepare_headmodel(cfg, segmentedmri);</p>
<p> </p>
<p>The vol and sensor locations were displayed and attached with here. </p>
<p> </p>
<p>How can I co-register the vol with sensors based on headshpe file (hs_file) for computing lead field for next step?</p>
<p> </p>
<p>Thanks a lot.</p>
<p> </p>
<p>Best regards,</p>
<p> </p>
