Array images that did not pass minimal quality thresholds were not used (median signal-to-background >3; median signal-to-noise >5; mean of median background signal <200).
Note that the minimal-quality thresholds of the subset selection methods can be obtained at the x-axis of the cumulative-percentage Figures 1b, 2b, 3b, 4b and 7b by choosing a percentage of subset size at the y-axis.
In a 2015 Resident Advisor feature called "The Online Underground: A New Kind of Punk," Harper suggests that "vaporwave is indeed punk in its crude and minimal quality," noting that its "threshold of participation is dramatically lower than punk rock's was—all you need is some very basic sound software (many use Audacity), some decent source material, a few clicks, and you're there".
Of these HQ reads, 57,997 exceeded our minimal quality standards (SMART primer filtering; length threshold of 50 bp) and were used in the assembly.
Since the base with the lowest quality value is most likely to cause misassembled contigs, the MinimalQ strategy identifies the minimal quality value of each read, and sets a threshold of selecting reads with minimal quality value no smaller than the threshold.
Raw trace files were processed using Trace2dbest [ 27], employing a Phred [ 28, 29] quality threshold of 20 and a minimal high quality sequence length of 150 base pairs (bp).
They suggest that, as the marginal cost of publishing a lot more material is minimal on the internet, all research that meets a certain quality threshold should be published online.
That is, a pair of reads will be selected if the minimal quality value of the two reads is larger than a given threshold.
To appear above the search results, ads must meet a certain quality threshold.
Would Twitter require some kind of quality threshold to allow advertisers to buy Promoted Moments?
