Hi to all, I have the following question. I used electa MEG system I have the MRI and the polhemus data for each subject. The MRI are in dicom and I can also transform it to 'analyze' format using SPM. The polhemus data are in fif format, together with the functional data. How can I coregister these two types of data? 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, Haris Styliadis
