By default, elements are phased and scaled prior to summation. Where a reference signal is not given, the mean dynamic signal will be used instead.

MRS data containing metabolite data.
MRS data containing reference data (optional).
MRS data from a noise scan (optional).
option to rescale coil elements based on the first data point (logical).
one of "sig_noise_sq", "sig_noise" or "sig".
sum the coil elements as a final step (logical).
the spectral region (in ppm) to estimate the noise.
take the mean of the reference scans in the dynamic dimension before use.
time-domain point to use for estimating phase and scaling values.
return the metabolite data only, even if reference data has been specified.
MRS data.
