The Reference Sequence (RefSeq) database [1] is an open access, annotated and curated collection of publicly available nucleotide sequences (DNA, RNA) and their protein products. RefSeq was introduced in 2000.
Checks for a start or stop codon in the reference genome sequence Internal stop: Checks for the presence of an internal stop codon in the genomic sequence NCBI:Ensembl protein length different: Checks if the protein encoded by the NCBI RefSeq is the same length as the EBI/WTSI protein NCBI:Ensembl low percent identity
Field 2 is the raw sequence letters. Field 3 begins with a '+' character and is optionally followed by the same sequence identifier (and any description) again. Field 4 encodes the quality values for the sequence in Field 2, and must contain the same number of symbols as letters in the sequence.
Slider is an application for the Illumina Sequence Analyzer output that uses the "probability" files instead of the sequence files as an input for alignment to a reference sequence or a set of reference sequences. Yes Yes No No [53] [54] 2009-2010 SOAP, SOAP2, SOAP3, SOAP3-dp SOAP: robust with a small (1-3) number of gaps and mismatches.
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.
The National Center for Biotechnology Information (NCBI) [1] [2] is part of the (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper.
MUltiple Sequence Comparison by Log-Expectation (MUSCLE) is a computer software for multiple sequence alignment of protein and nucleotide sequences. It is licensed as public domain. The method was published by Robert C. Edgar in two papers in 2004. The first paper, published in Nucleic Acids Research, introduced the sequence alignment algorithm ...
Make a k-letter word list of the query sequence. Take k=3 for example, we list the words of length 3 in the query protein sequence (k is usually 11 for a DNA sequence) "sequentially", until the last letter of the query sequence is included. The method is illustrated in figure 1. Fig. 1 The method to establish the k-letter query word list. [14]
