Optical mapping [1] is a technique for constructing ordered, genome-wide, high-resolution restriction maps from single, stained molecules of DNA, called "optical maps". By mapping the location of restriction enzyme sites along the unknown DNA of an organism, the spectrum of resulting DNA fragments collectively serves as a unique "fingerprint" or "barcode" for that sequence.
Deployment flowcharts consist of a sequence of activity steps, as well as the interactions between individuals or groups. [1] Each participant in the process is displayed on the map (which is constructed as a matrix) - tasks/activities are then articulated in sequence under the column corresponding to that stakeholder.
At this step, sequencing reads whose quality have been improved are mapped to a reference genome using alignment tools like BWA [17] for short DNA sequence reads, minimap [18] for long read DNA sequences, and STAR [19] for RNA sequence reads. The purpose of mapping is to find the origin of any given read based on the reference sequence.
During sequencing, each base in the template is sequenced twice, and the resulting data are decoded according to this scheme. 2 Base Encoding , also called SOLiD ( sequencing by oligonucleotide ligation and detection ), is a next-generation sequencing technology developed by Applied Biosystems and has been commercially available since 2008.
Most high-throughput, next generation sequencing platforms produce shorter read lengths compared to Sanger sequencing.These new platforms are able to generate large quantities of data in short periods of time, but until methods were developed for de novo assembly of large genomes from short read sequences, Sanger sequencing remained the standard method of creating a reference genome.

RseqFlow is an RNA-Seq analysis pipeline which offers an express implementation of analysis steps for RNA sequencing datasets. It can perform pre and post mapping quality control (QC) for sequencing data, calculate expression levels for uniquely mapped reads, identify differentially expressed genes, and convert file formats for ease of ...
Sequence Alignment Map (SAM) is a text-based format originally for storing biological sequences aligned to a reference sequence developed by Heng Li and Bob Handsaker et al. [1] It was developed when the 1000 Genomes Project wanted to move away from the MAQ mapper format and decided to design a new format.
Once the query sequence is uploaded/pasted into the search field, the user can select various parameters such as which species' genome to target (there are currently over 50 species available) and the assembly version of that genome (for example, the human genome has four assemblies to select from), the query type (i.e. whether the sequence ...
