[FieldTrip] EEG electrode coordinates

[Holly Rossiter]

Hi there,

Our student is using a novel method for coregistering EEG electrodes and fiducials using a number of cameras. We therefore have just a list of coordinates and fiducials that doesn't come from a standard software package like polhemus for example. We are having trouble reading it in to use in ft_electroderealign/ft_volumerealign/ft_read_headshape in a form that fieldtrip is happy with as it asks for units and a coordinate system that it recognises whereas ours is sort of arbitrary. Is there any way to create the correct structure so that we can use these coordinates for EEG coregistration with an MRI?

Kind regards,
Holly
