Dear all,<br><div class="gmail_quote"><div><br></div><div>I am creating headmodels of neuromag data (Using FT version 20123105 and the example script <a href="http://fieldtrip.fcdonders.nl/example/create_single-subject_grids_in_individual_head_space_that_are_all_aligned_in_mni_space" target="_blank">http://fieldtrip.fcdonders.nl/example/create_single-subject_grids_in_individual_head_space_that_are_all_aligned_in_mni_space</a>) </div>
<div><br></div><div>The 'vol' structure is created like this:</div><div><br></div><div><div>cfg = [];</div><div>cfg.coordsys = 'neuromag'; </div><div>cfg.method = 'singleshell';</div>
<div>cfg.sourceunits = 'mm'; % I have been playing with different units here</div><div>vol = ft_prepare_singleshell(cfg, segmentedmri);</div></div><div><br></div><div>the 'grid' like this:</div><div><br>
</div><div><div>load(strcat(basepath,'templates/template_grid.mat'));</div><div>cfg = [];</div><div>cfg.grid.warpmni = 'yes';</div><div>cfg.grid.template = template_grid;</div><div>
cfg.grid.nonlinear = 'yes'; % use non-linear normalization</div>
<div>cfg.coordsys = 'neuromag'; </div><div>cfg.sourceunits = 'm'; % I have been playing with different units here as well (the template grid resolution is 1 cm)</div><div>cfg.mri = mri;</div>
<div>cfg.vol = vol;</div><div>grid = ft_prepare_sourcemodel(cfg);</div><div>save(strcat(basepath,cases{s},'brain.mat'), 'vol','grid');</div></div><div><br></div>
<div>Everything works well, untill I plot and see that the sizes/ origins (or units) are completely different for the vol and grid. At the moment I cannot find a solution. Does anyone have an idea?</div><div>The results are plotted and attached to this e-mail.</div>
<div><br></div><div>Thanks in advance,</div><div><br></div><div>Hanneke</div><div><br></div><div><br></div><div><br></div><div><p><span style="font-size:9.0pt">__________________________________________</span></p>
