CTF 3rd order gradiometers correction

[Suresh Muthukumaraswamy]

Hi,
 as far as I am aware fieldtrip reads in whatever gradiometer definition your data is saved as and
doesnt apply any other processing to this
You can check what the gradiometer definition of the saved data is  in DataEditor.
In the Acq software you can pick what type of gradiometers the data is saved as. We usually just
save it as 3rd order in the data at the Acq level and you dont have to worry about it from then on
(unless you had some reason to undo the 3rd order gradiometers)

Hi All
CTF software allows to open a MEG dataset and to apply a theoretical 3rd
order gradiometers data correction, which makes use of a number of
coefficients to correct raw data from common mode artifacts.
Does Fieldtrip take in account this correction as well?
Where is it coded?
Regards
Cristiano
