Web(A) All reads are stored in a hash table with a unique id. 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. http://www.cs.otago.ac.nz/cosc348/alignments/Lecture06_LocalAlignment.pdf WebTo save space, the hash table supports variable length counter, i.e. a k-mer occurring only a few times will use a small counter, a k-mer occurring many times will used multiple … lego heartlake city rush
