-------------------------------------------------------------------------------------------------
For subject 1
-------------------------------------------------------------------------------------------------

Every acuisition contains 2 datasets: S1_Acq_[number].sid and S1_Acq_ref_[number].sid
S1_Acq_[number].sid is the metabolite spectra
S1_Acq_ref_[number].sid is the water reference spectra


Every dataset for subject 1 has a matrix of 2*1024*42*65*7 (complex number * spectral points * x voxels * y voxels * z voxels)
It can be read by MATLAB using 

FileID = fopen('locazion of data.sid');
A = fread(FileID ,'flooat32');

and reshaped using 

B = reshape(A,2,1024,42,65,7);

 
-------------------------------------------------------------------------------------------------
For subject 2, measurement 1 before alpha-D-glucose uptake
-------------------------------------------------------------------------------------------------

Every acuisition contains 2 datasets: S2_M1_Bef_Acq_[number].sid and S2_M1_Bef_Acq_ref_[number].sid
S2_M1_Bef_Acq_[number].sid is the metabolite spectra
S2_M1_Bef_Acq_ref_[number].sid is the water reference spectra


Every dataset for subject 2 has a matrix of 2*1024*42*65*9 (complex number * spectral points * x voxels * y voxels * z voxels)
It can be read by MATLAB using 

FileID = fopen('locazion of data.sid');
A = fread(FileID ,'flooat32');

and reshaped using 

B = reshape(A,2,1024,42,65,9);


-------------------------------------------------------------------------------------------------
For subject 2, measurement 1 after alpha-D-glucose uptake
-------------------------------------------------------------------------------------------------

Every acuisition contains 2 datasets: S2_M1_Aft_Acq_[number].sid and S2_M1_Aft_Acq_ref_[number].sid
S2_M1_Aft_Acq_[number].sid is the metabolite spectra
S2_M1_Aft_Acq_ref_[number].sid is the water reference spectra


Every dataset for subject 2 has a matrix of 2*1024*42*65*9 (complex number * spectral points * x voxels * y voxels * z voxels)

A = fread(FileID ,'flooat32');

and reshaped using 

B = reshape(A,2,1024,42,65,9);


-------------------------------------------------------------------------------------------------
For subject 2, measurement 2 before equilibrium alpha/beta-D-glucose uptake
-------------------------------------------------------------------------------------------------

Every acuisition contains 2 datasets: S2_M2_Bef_Acq_[number].sid and S2_M2_Bef_Acq_ref_[number].sid
S2_M2_Bef_Acq_[number].sid is the metabolite spectra
S2_M2_Bef_Acq_ref_[number].sid is the water reference spectra
