DivergentSet: picking non-redundant sequences from large sequence collections

Selection of Oligonucleotide Probes for Protein Coding Sequences

MOTIVATION Large arrays of oligonucleotide probes have become popular tools for analyzing RNA expression. However to date most oligo collections contain poorly validated sequences or are biased toward untranslated regions (UTRs). Here we present a strategy for picking oligos for microarrays that focus on a design universe consisting exclusively of protein coding regions. We describe the constra...

Removing near-neighbour redundancy from large protein sequence collections

MOTIVATION To maximize the chances of biological discovery, homology searching must use an up-to-date collection of sequences. However, the available sequence databases are growing rapidly and are partially redundant in content. This leads to increasing strain on CPU resources and decreasing density of first-hand annotation. RESULTS These problems are addressed by clustering closely similar s...

RSAT matrix-clustering: dynamic exploration and redundancy reduction of transcription factor binding motif collections

Transcription factor (TF) databases contain multitudes of binding motifs (TFBMs) from various sources, from which non-redundant collections are derived by manual curation. The advent of high-throughput methods stimulated the production of novel collections with increasing numbers of motifs. Meta-databases, built by merging these collections, contain redundant versions, because available tools a...

Sma3s: A Three-Step Modular Annotator for Large Sequence Datasets

Automatic sequence annotation is an essential component of modern 'omics' studies, which aim to extract information from large collections of sequence data. Most existing tools use sequence homology to establish evolutionary relationships and assign putative functions to sequences. However, it can be difficult to define a similarity threshold that achieves sufficient coverage without sacrificin...
