    Hello!
    Could you please tell which method of Noise SD estimation is used in Amares?

    In jMRUI, the noise standard deviation can be estimated from the residue, the last points of the raw signal or from a known value in case of simulations. Users define the value used in the estimation of the standard deviation on metabolite amplitudes (AMARES, QUEST, etc.) in the Results window.

    Dear all,

    Could you tell how exactly the value of S/N is calculated in AMARES (using the noise of the residu)? In other words, what is the exact formula and with which values in the results table is it calculated?

    Thanks very much,
    Best regards,
    Harmen

    @Harmen
    Just look the the explanation in [jmrui_folder]/doc/Noise_STD_LCRB.pdf
