Default behavior ¶. By default, bedtools flank will either add a fixed number of bases in each direction ( -b) or an asymmetric number of bases in each direction with -l and -r. However, if the requested number of bases exceeds the boundaries of the chromosome, bedtools flank will “clip” the feature accordingly.

Beyond transcripts. Current HGVS recommendations state (see Reference Sequences): “5’ and 3’ flanking sequences are considered to be outside the boundaries of a transcript reference sequence and can not be used to describe variants”.As a consequence, variants removing an entire gene or the 5’ or 3’ end of a transcript can only be described using …Intron-flanking primers designed from alignment of conserved DNA sequences flanking introns common to seven sequenced angiosperm mitochondrial genomes (Grosser, 2011) generate intron amplification products that distinguish C. maxima from C. reticulata (Satpute et al., 2015) and C. maxima from C. japonica (kumquat) (Omar et al., 2017).

Oncogene 5 ...Human experts are good at summarizing explicit strong patterns from small samples, while deep learning models can learn implicit weak patterns from big data. Biologists have traditionally described the sequence patterns of promoters via transcription factor binding sites (TFBSs), while the flanking sequences among TFBSs, which can …

These clusters, known as 'flank patterns' (FPs), are based on Mash distances, allowing for easy comparison of similarity across sequences. Additionally, Flanker can be flexibly parameterized to fine-tune outputs by characterizing upstream and downstream regions separately, and investigating variable lengths of flanking sequence.
