Top: Example spectrum from a representative migraine patient from the occipital voxel position. The red line is the LCModel fit of the data from this patient, the thin black line with the same shape as the red fit is the raw data. The baseline is the thin black line lowest in the spectrum. At the top of the plot is the residuals of the fitted raw data to the model, i.e. the raw data minus the fitted data. Quality data: for this spectrum: S/N 101 and a delta shift of 0.004 ppm, FWHM = 0.028 ppm. Bottom: The GABA fit from the same spectra
