In this tutorial, it seems I have to have a “-trans.fif” file to be able to do the computations for source-localized data. However, I cannot find such a file in my freesurfer results. Shall this file be obtained through MRI? I also just have “.con” files as my MEG files.
I will put screenshot of my MRI directory:
Which of these files should I use for -trans file? If it is not listed here, how should I obtain it?
Thanks in advance
