**** Content *********

The variables below were processed after zerofiling and filtering the raw data, as described in Methods.
The final wave information, which can be used for mechanical properties reconstruction 
is "combinedWave_unwrapped", and its mask is "combinedMask".

combinedMask: 			3D dataset, boolean mask of object vs background for zerofilled-wave data
combinedWave: 			3D dataset, real data of final wave Psi obtained after processing step 3 in Fig. 1
combinedWave_unwrapped: phase-unwrapped combinedWave (obtained using robustunwrap)
xi_meg:					5D dataset [3D for 2 RX channels (5th dimension), 4th dimension = 1], complex motion-encoded data obtained after processing step 1 in Fig. 1, motion-encoded acquisition with vibration
xi_ref: 				as xi_meg, acquired without vibration (reference)
sequenceParameters:     details of the employed sequences used to acquire the raw data (cf. sequenceParameters.cameleon and Table 4 in the manuscript)



*** Raw data ***

[5D datasets, 4th dimension: MEG polarity, 5th dimension: RX channel]

data_vib: 		raw k-spaces, non-zerofilled and non-filtered, motion-encoded acquisition with vibration
data_ref: 		as data_vib, acquired without vibration (reference)
