[Mne_analysis] forward model having only segmentation files

[tokariev at mappi.helsinki.fi]

Hello Alex,

Thank you very much for your reply. I completely understand that it is  
better to use Freesurfer first. But I deal with neonatal data. And  
Freesurfer, unfortunately, fails to analyse such kind of data (when I  
tried it even did not create all folders and files, those i could edit  
manually). As far as I got from literature, people (almost) always do  
segmentation of neonatal data manually and then launch Freesurfer. But  
it takes a lot of time to do and is not trivial task. But I have  
already segmentation files done in FSL. So, my idea was somehow to use  
them in MNE to get forward model. What would you recommend? What do  
you think the most optimal way to act in my case?

Regards,
Anton
