Distance between Head and sensors

[SBeumer]

Hi Afo,

Usually the information is in the dataset , because the location of the head is quite important in that kind of systems.

You might find your answer in the following thread about MEG sensors:

Senors organisation

The file coil_def.dat contains the geometry of various types of MEG sensors, independently from any acquisition device. The functions mne_add_coil_defs.m or ctf_add_coil_defs.m apply this geometry to the description of an acquisition device (position and orientation of each sensor in the MEG system), as it can be found in a .fif file (Elekta) or .res4 file (CTF). https://github.com/mne-tools/mne-matlab/blob/master/matlab/mne_add_coil_defs.m https://github.com/brainstorm-tools/brainstorm3/blob…

Kind regards,
Steven
