How to create trans.fif file from MNE-Analyze

External Email - Use Caution

I'm performing source localization on MEG data. Using MNE python, I have
done some analysis part but for source localization, it requires additional
input files which I have generated using Freesurfer.
It is suggested to create trans.fif file using MNE-Analyze. Is there any
tutorial on how to create trans.fif file using MNE-analyze.

Another question I have is: my MEG data is resting state and it is already
preprocessed but when doing it with MNE-python as per the tutorial for
source localization, it asks for epochs, events, which in my case does not
have. How to deal with such data or how to perform source localization with
resting state M

hi,

you may want to look at :
https://www.slideshare.net/mne-python/mnepythyon-coregistration-28598463
if you want to do it with MNE-Python.

or look at section 7.16 in
http://www.martinos.org/meg/manuals/MNE-manual-2.7.pdf

to get events for rest data use
