WebFASTA is a DNA and protein sequence alignment software package first described by David J. Lipman and William R. Pearson in 1985. [1] Its legacy is the FASTA format which is now ubiquitous in bioinformatics . History [ edit] The original FASTA program was designed for protein sequence similarity searching. WebHash Functions. A hash function, h, maps keys of a given type to integers in a fixed interval [0, N - 1] Example: h (x) = x. mod . N. is a hash function for integer keys. The integer . h (x) is called the hash value of . x. A hash table for a given key type consists of. Hash function . h. Array (called table) of size . N.

"WebReading and encoding kmers from a FASTA/FASTQ file is achieved in KAGE by using BioNumPy , a Python library built on top of NumPy . BioNumPy uses NumPy to efficiently read chunks of DNA reads from fasta files, encode the bases to a 2-bit representation, and then encode the valid kmers as 64-bit integer representations in an array.
