"WebMay 3, 2024 · Here is a very basic table for some high performance hash table I found. The input is 8 M key-value pairs; size of each key is 6 bytes and size of each value is 8 bytes. The lower bound memory usage is ( 6 + 8) ⋅ 2 23 = 117MB . Memory overhead is computed as memory usage divided by the theoretical lower bound. " - Hash table in fasta bioinformatics ppt

A second hash table contains the ids for the read start = k-mer parameter (default = 38) of the corresponding read. (B) Scope of search 1 is the region where a match of the ‘read start’ indicates a extension of the sequence. All these matching reads are stored separately.

Local alignment – focuses on region of similarity in parts of the sequence only.

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.
