Results of the consensus rating of spectral quality by a panel of MR spectroscopy experts. Each spectrum was reviewed independently by three experts, who gave it a label of “Good” (G), “Acceptable” (A), or “Poor” (P) quality. After discarding spectra with strong disagreement between reviewers, the final data set was split into 80:10:10 partitions of training, validation, and testing data sets.

Reviewer Labels			Consensus Label		# of Spectra	% of Total
G	G	G	Good		360	4.05
G	G	A	Good		914	10.28
G	A	A	Acceptable		1597	17.96
A	A	A	Acceptable		1672	18.80
A	A	P	Acceptable		1448	16.28
A	P	P	Poor		1120	12.59
P	P	P	Poor		1356	15.25
G	G	P	Discarded		23	0.26
G	A	P	Discarded		355	3.99
G	P	P	Discarded		49	0.55
