Differential hybridization to perfect match (PM) vs mismatch (MM) oligo probes on the Affymetrix chip was used to identify transcripts reliably detected as "present" in the Reference and unc-4 GFP unc-4 GFPon data sets (see motords, Additioneuronles 4, 5).
For basic reference items, the Contrast-values have always been determined with respect to the same reference score values from the visit at which the items were detected as reference items, i.e. the values for the pre-treatment 'visit'visit
Once an item has been detected as a reference item, its Contrast-values contribute to the TDC-values of subsequent visits.
When the same item is detected as an added reference item during treatment as well as at the first post-treatment visit, its Contrast-value at the first post-treatment visit might differ between the modes of separately added reference items from clinician and assessor and continued added items respectively.
The barley ADP-ribosylation factor 1-like [GenBank: AJ508228.2] gene fragment of 61 nt was simultaneously amplified and detected as an internal reference [ 77].
VNTRfinder allows filtering to only report repeat variants representing length changes consistent with changes in the copy-number of the tandem repeat unit detected in the reference, as in [ 2], with the additional check that the bases differing in the insertion/deletion event actually correspond to the tandem repeat unit.
Each query SSR locus detected in the reference is defined as a conserved SSR, although we cannot rule out the possibility that a SSR was lost during evolution within a species or lineage and independently a new, nonhomologous SSR with the same motif arose at the same or very similar position.
Correspondingly, the number of sites where both methods detected no deviation from the reference sequence divided by the number of sites where the microarray detected only the reference residue was used as an estimate of the specificity.
The pseudo-autosomal regions of the X-chromosomes are exceptions, but CNVs there can be detected as a function of the reference set used in the analysis.
Elements that were deleted from this reference should then be detected as insertions in the resequencing data of the reference strain Col-0, and the positions of the deleted elements have been used to benchmark the predictions of Jitterbug and RetroSeq.
