The phrase "flags present" is correct and can be used in written English.
It means that there are indicators or signals present that suggest a certain situation or condition. Example: "Upon entering the store, there were several flags present that hinted at a clearance sale. I immediately headed to the discounted section."
Following 75th percentile shift normalization, low-intensity probes subject to high degrees of noise were removed by filtering the lowest 20% of each sample and then by filtering with flags (present and marginal).
Most importantly, these flags present a different aspect ratio (proportions), which gives each one a unique look.
Analysis used were filter on flags (present or marginal) were 27194 probes (out of 41078) passed in 2 out of 4 technical replicates with tumor tissue.
Average linkage hierarchical clustering was carried out on genes filtered on detection flags ("present" in two or more cell lines) and signal intensity (>50 in all cell lines).
Genes in Ypr013CΔ or Ypro015CΔ single mutant and double mutants (Ypr013CΔ Ypro015CΔ) were filtered based on flags present in four out of eight samples.
To assess the performance of each microarray platform we compared the complete content (all probesets) of the arrays based on detection (Flags, present or marginal) and detection plus differential expression.
On June 11 and 12, Six Flags presents the Geico P.B.A. Team Shootout, during which nearly two dozen bowlers from the Professional Bowlers Association will compete on specially constructed lanes within the park.
Ceremonies are held, flags presented, tributes published.
As in a melodrama, you know that the flags presented in the first act are going to come into play in the fourth (they turn out to be sheets of fresh pasta, meant to be wrapped around braised shortribs, with dabs of fermented garlic, smoked salt, halved blackberries and tobacco sabayon).
The flag present, and old soldiers.
All the genes with flag present in at least 100% of the values in any 1 out of the 6 conditions (see Table 1) were considered.
