Dear Maria,

the easiest way to use a headmodel without the mri, is to use a template head model.
You can find some info about under http://www.fieldtriptoolbox.org/template

Thanks a lot! ft_mergealign seems to need the head model.
Could you please yet let me know it is possible to create the head model without mri data?

Best,
Maria

Subject: [FieldTrip] How to move subjects’ heads into a same position?

Hi all,

I wonder if field trip has any function that could be used to transfer all the subjects’ heads into a same position, so that the sensors correspond better to each other? I have done this before using maxfilter with -trans option. However, I don't have neuromag data now and, therefore, I can't use maxfilter.

Best,
Maria
