But the flimsy flatness of the facade belies the complexity within, where theatrical stairs, overscaled architraves and ambiguous thresholds produce a finely crafted sequence.
Secondly, the false positives could arise from sequencing errors introduced by the combination of lower quality reads (especially for the mutations identified from the "low group") and the ambiguous mutation detection threshold.
Trimming eliminates the 3' end with above-threshold ambiguous base calls, but the remaining sequence still contains errors.
These include limiting the amount of political activity by a 501(c)(4) group to a specific 10 or 20percentt of its total work -- rather than the more ambiguous under-50-percent threshold that is assumed to be used (but not confirmed) by the IRS.
In particular, we found that a threshold of.5% ambiguous nucleotides yields a negative predictive value of 98.7%.
False positive PHASE inferences, defined here as ambiguous genotypes for which above-threshold haplotype pair reconstructions included errors, were generally very low (Table 3).
The three parameters of Hammer are: τ, the joining distance for k-mers, singletonCutoff, the threshold for singleton and ambiguous clusters, saveCutoff, the threshold above which k-mers are never removed, and the k-mer size.
Clones located close to the threshold were scored as ambiguous.
If there were no barcodes in the library within the threshold, the assignment was "ambiguous".
However, the decision to begin the process of restructuring is a difficult and critical choice for most decision makers due to the fact that the decision threshold of the process is ambiguous.
