Hi Tolga,
<div><br>
</div>
<div>There’s a layout that ‘better fits’ the projected channel locations, and which you can obtain from the megconnectome software that accompanies the HCP MEG data. The software can be obtained from here:
<a href="http://humanconnectome.org/documentation/MEG1/meg-pipeline.html">humanconnectome.org/documentation/MEG1/meg-pipeline.html</a></div>
<div>If you download one of the packages and unzip it, you’ll find a ‘template’ directory. Inside, there’s a 4D248.mat file (note that you need the ‘4D248.mat’ in cfg.layout in that case), which you can use as a layout for visualization.</div>
<div><br>
</div>
<div>Best wishes,</div>
