[FieldTrip] Rotating sensors using ft_transform_sens

[Julian Keil]

Dear Ulrich,

could you use ft_electroderealign with the interactive-option instead?
Here you have an graphic interface that lets you rotate the electrodes in all directions to match your headshape.
ft_transform_sens is used in this function, so the output should be the same.
Moreover, if you check the code of ft_electroderealign, it can give you a hint to what the transform-matrix should look like: I think it should be a 3x3-matrix with scale, transform and rotate xyz-vectors.

I hope this helps,

Julian
