RECONSTRUCTING A SUFFIX ARRAY [PDF]
For certain problems (for example, computing repetitions and repeats, data compression applications) it is not necessary that the suffixes of a string represented in a suffix tree or suffix array should occur in lexicographical order (lexorder). It thus becomes of interest to study possible alternate orderings of the suffixes in these data structures,

Fast Hybrid Data Structure for a Large Alphabet K-Mers Indexing for Whole Genome Alignment
The most common index data structures used by whole genome aligners (WGA) are based on suffix trees (ST), suffix arrays, and FM-indexes. These data structures show good performance results as WGA works with sequences of letters over small alphabets; for ...

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.

GHOSTX: an improved sequence homology search algorithm using a query suffix array and a database suffix array. [PDF]
DNA sequences are translated into protein coding sequences and then further assigned to protein families in metagenomic analyses, because of the need for sensitivity.

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 ...

Generalized enhanced suffix array construction in external memory
Background Suffix arrays, augmented by additional data structures, allow solving efficiently many string processing problems. The external memory construction of the generalized suffix array for a string collection is a fundamental task when the size of ...

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.

TOPAZ: asymmetric suffix array neighbourhood search for massive protein databases
Background Protein homology search is an important, yet time-consuming, step in everything from protein annotation to metagenomics. Its application, however, has become increasingly challenging, due to the exponential growth of protein databases.
