Take a long strip and apply length-wise, securing the front and back.
By applying length, %GC and conservation thresholds we have significantly enriched our list of IGRs for known structured RNAs.
Specifically, it rescales optical map and applies length constraint for selecting the correct contig sequences for gap closure.
More importantly, it applies length constraints, uniqueness of contig alignment, and a loop-path recording method to avoid deep recursion.
OMACC is advantageous because it takes into account gap size carefully via rescaling optical map and applying length constraint on selecting the path of contigs for gap closure.
For IMEx pattern search, we used the previously applied length threshold parameters (Mono-, 12; Di-, 6; Tri-, 4; and for Tetra- to Hexa- repeats, a minimum stretch of three minimum repetitions) (9).
Raw sequencing data were processed with the ACGT-miR-v3.5 package (LC Sciences) to filter out adaptors, technical impurities, repetitive sequences, and low-quantity reads (<3) while applying length-cutoff values (15 26 nt), resulting in a nonredundant sequence list.
Also some of the systems did apply a length cut-off when detecting chemicals, especially those that relied chemical dictionary lookup as the recognition approach.
Alignment to the transcriptome allows us to capture junction-spanning reads and to apply appropriate length adjustments.
To our knowledge, we are the first to apply variable length motif models to eukaryotic ChIP-seq data sets and consequently the first to show their value in this domain.
