Hi to all,
I just started using fieldtrip and I have the following question.
I have the MRI and the polhemus data for each subject.
The MRI is in dicom and I can also transform it to 'analyze' format using
The polhemus data are in fif format, together with the functional data.
How can I coregister these two types of data in fieldtrip?
I searched in the tutorial and it is mentioned that normally MEG systems
come with a software allowing to align MRI with the helmet, e.g. CTF.
However, I have worked on Neuromag system and I have not done anything like
this. How can I do it in Fieltrip?
A step by step (AC-PC points, normalization, segmentation etc) guidance
would be very helpful stating the functions I have to use and any
precautions I have to consider during this process.
Best regards and thanks in advance,
