Compressed Spaced Suffix Arrays [PDF]
Spaced seeds are important tools for similarity search in bioinformatics, and using several seeds together often significantly improves their performance. With existing approaches, however, for each seed we keep a separate linear-size data structure, either a hash table or a spaced suffix array (SSA). In this paper we show how to compress SSAs relative

Suffix Arrays in Parallel [PDF]
Suffix arrays are powerful data structures for text indexing. In this paper we present parallel algorithms devised to increase throughput of suffix arrays on a multiple-query setting. Experimental results show that efficient performance is indeed feasible in this strongly sequential and very poor locality data structure.

Locally Compressed Suffix Arrays [PDF]
We introduce a compression technique for suffix arrays. It is sensitive to the compressibility of the text and local , meaning that random portions of the suffix array can be decompressed by accessing mostly contiguous memory areas. This makes decompression very fast, especially when various contiguous cells must be

The suffix array is a classic full-text index, combining effectiveness with simplicity. We discuss three approaches aiming to improve its efficiency even more: changes to the navigation, data layout and adding extra data. In short, we show that i) the way how we search for the right interval boundary impacts significantly the overall search speed, ii ...

Suffix-Sorting via Shannon-Fano-Elias Codes
Given a sequence T = t0t1 . . . tn-1 of size n = |T|, with symbols from a fixed alphabet Σ, (|Σ| ≤ n), the suffix array provides a listing of all the suffixes of T in a lexicographic order.

Costruzione space efficient di un suffix tree troncato con codifica TruST [PDF]
Argomento della tesi è il suffix tree troncato, che ha la struttura ad albero ma occupa meno spazio del suffix tree. Il procedimento originariamente usato nella costruzione del suffix tree troncato con codifica TruST si basa sulla codifica derivata da ...

GeDi: applying suffix arrays to increase the repertoire of detectable SNVs in tumour genomes
Background Current popular variant calling pipelines rely on the mapping coordinates of each input read to a reference genome in order to detect variants.

Fast Lightweight Suffix Array Construction and Checking [PDF]
We describe an algorithm that, for any $v\in[2,n]$, constructs the suffix array of a string of length $n$ in $\Oh{vn + n \log n}$ time using $\Oh{v+n/\sqrt{v}}$ space in addition to the input (the string) and the output (the suffix array). By setting $v=\
