In the chapter “Head model and forward computation” it says that one can obtain the “trans file” with mrilab if one uses a Neuromag system. But I don’t understand how to obtain the “trans.fif”-file with mrilab.
I coregister the MRI to the digitized points (Nas,LPA,RPA, Coils) from the MEG measurement and save the fiducial coordinates in a .txt file (which can be either stored in “head”, “MRI” or “voxel” coordinates) and the coregistered mri.fif file. But from these two files I don’t know how to create the trans.fif file and I don’t see any option in mrilab to create a trans.fif file. I know that I could use mne.gui.coregistration or men_analyze. But as I’ve already done the coregistration in mrilab I wouldn’t want to do everything again.
It would be great if someone could help me!
