The other challenge to historical methods is the preponderance of false-positives derived from a confirmation bias that affects individuals, teams, and organizations.
Although putative elemental compositions could be assigned to many metabolite signals using these methods, it should be noted that incorrect hits (i.e., false positives) derived from errors in mass analyses will be included in the search results [17].
Our current study shows that Pkd1-mutant endothelial cells (CD31-positive) derived from the metanephric organ cultures are impaired in their capability to migrate.
These procedures should be able to remove false positives derived from internal polyA stretches and low quality base calls.
For instance, genuine TSSs mapped by transcription initiation mapping are diluted by false positives derived from RNA processing or degradation.
Candidate biomarkers often lack diagnostic utility because of poor sensitivity (false negatives) and/or inadequate specificity (false positives) derived from confounding exposures, nonspecific biomarkers or individual variability.
However, these TSSs can be validated by RNAP FP since false positives derived from RNA degradation or processing are excluded by the second experiment.
However, these are not suited to reduce the number of false positives derived from non-random RNA degradation (43), stochastic transcriptional events (10) and PCR biases that arise during library construction.
However, we added a warning concerning the possible spurious cancer associations for 60 genes (39 olfactory receptors, 14 genes with long exons and/or introns and 7 additional false positives derived from literature (7).
The false positives derived from the evaluation can also be considered as drug repurposing hypotheses: these drugs can indeed be interpreted as suitable for the ATC category, yet not indexed as such.
To ensure the identified polyadenylation site are not false positives derived from low quality base calls, reads with quality scores in any of the upstream and downstream 5 nt flanking the polyadenylation site less than 20 were further removed.
