Hi,

I just wanted to ask/make one point.

Can you clarify a bit as to what you are referring to as a "technical
replicate" in this sense?

You could consider two lanes that are sequenced from the same library
as technical replicates, no? Or, by "technical replicate" do you mean
creating two libraries out of one sample?

If we're talking about the former, then I think there is lots of value
to be gained, and perhaps necessary(?), to running more than one lane
per library preparation -- and maybe the question would rather be "how
many lanes to run per library"?

What does the court think?
