Does the phrase "a minimum of" in conjunction with a plural term require a singular or plural verb?
"A minimum of 1.6 million reads was generated per sample."
vs.
"A minimum of 1.6 million reads were generated per sample."
Edit 1: I suppose that the situation is similar to using the collective noun "a total of", in which case a plural verb would be required ("A total of 10 babies is..." vs. "a total of 10 babies are..." vs. "Ten babies in total are...")
