K-mer frequency vector

WebSep 1, 2024 · A k -mer is defined as a short subsequence of the DNA (nucleic acid) or protein (amino acid) sequence. The length of a k -mer is defined by the value of k (e.g., if k = 4, then the k-mer length is 4 base pair). In the case of DNA sequences, a k -mer is composed of k random letters from the alphabet . The frequency of a set of k-mers in a species's genome, in a genomic region, or in a class of sequences can be used as a "signature" of the underlying sequence. Comparing these frequencies is computationally easier than sequence alignment and is an important method in alignment-free sequence analysis. It … See more In bioinformatics, k-mers are substrings of length $${\displaystyle k}$$ contained within a biological sequence. Primarily used within the context of computational genomics and sequence analysis, in which k-mers are … See more The frequency of k-mer usage is affected by numerous forces, working at multiple levels, which are often in conflict. It is important to note that k-mers for higher values of k are … See more • Oligonucleotide • Genomic signature See more • bioXriv:k-mer • arXiv: k-mer See more k-mers are simply length $${\displaystyle k}$$ subsequences. For example, all the possible k-mers of a DNA sequence are shown below: See more Pseudocode Determining the possible k-mers of a read can be done by simply cycling over the string length by one and taking out each substring of length $${\displaystyle k}$$. The pseudocode to achieve this is as follows: See more
