Results:


1D Shimming:
Low S/N encountered. The acquisition parameters will be changed to improve this issue.
Iteration  1: FWHM Before=18.2 Hz, Target= 0.4 Hz, After= 0.3 Hz
Iteration  2: FWHM Before= 0.3 Hz, Target= 2.1 Hz, After=19.0 Hz
Iteration  3: FWHM Before=19.0 Hz, Target= 0.2 Hz, After= 9.5 Hz
Iteration  4: FWHM Before= 9.5 Hz, Target= 6.6 Hz, After= 0.2 Hz
Iteration  5: FWHM Before= 0.2 Hz, Target= 6.6 Hz, After= 0.7 Hz
Iteration  6: FWHM Before= 0.7 Hz, Target= 3.8 Hz, After= 5.7 Hz
Iteration  7: FWHM Before= 5.7 Hz, Target= 0.2 Hz, After= 0.2 Hz
