Hi Maria,

I haven't found any disadvantages in doing it so I think it's a good idea. There is some code in MEEGTools for using the head tracking data. For instance you can recompute the sensor locations based just on parts of the data that you are using or exclude some data based on head location/movement. But this is mostly useful if you do source localisation and if you have subjects that cannot keep still. For most normal controls the head is quite stable.

Hi Vladimir,

I have started MEGing again!

Wanted to ask you if there is any real advantage to doing continuous head localization (rather than just before and after the block).

What is the data used for?

 

Thanks,
