The phrase "alignment of variable" is not correct in standard written English.
It seems to be a truncated or incorrect version of a more complete phrase, possibly referring to "alignment of variables" in a statistical or programming context.
Example: "The alignment of variables in the dataset is crucial for accurate analysis."
Alternatives: "adjustment of variables" or "synchronization of variables."
The primers were designed, by multiple sequence alignment of variable regions, specific for cold-adapted donor virus HTCA-A101, as compared to other influenza A viruses.
Additional file 5: Alignment of variable domains from SCAmpPs-3 and -4 promoters 130 bp 5′ to the transcription start.
Strong between- and/or within-population differentiation of haplotypes indicative of local or partial selective sweeps are observed in the alignment of variable sites in candidate genes harboring the strongest signals (e.g. Additional file 8: Figure S8).
Valimaki et al. (2007) have previously explored the use of BWT compressed self-index methods for efficient compression and search of genetic sequence data from many individuals, but this does not require a fixed alignment of variable sites as in the work presented here, and is substantially different.
Alignments of variable positions are provided in supporting information figures (Figure S1, S2, S3, S4).
Like Bockhorst et al. have shown for the DBL2X domain [24], we have developed an expanded alignment to study local alignments of variable blocks from DBL6ε domains.
As measuring the effect of some of these factors is a complicated issue and beyond the scope of this work, alignments of variable read and reference lengths were used in comparing reads misalignments of Eland, RMAP and Slider.
The alignment of 72 variable sites is shown in Fig 2.
Table 1 displays the alignment of demographic variables for this sub-study sample and the overall ACCORD trial.
The alignment of these variables with the biopsychosocial model was a further consideration for inclusion in the study.
The linkage facility of DVA records enabled measurement of total LOS, a wide search field for comorbidities, accurate matching of RAC status with fracture events and alignment of specific variables with components of LOS.
