VisualRepbase: an interface for the study of occurrences of transposable element families

BackgroundRepbase is a reference database of eukaryotic repetitive DNA, which includes prototypic sequences of repeats and basic information described in annotations. Repbase already has software for entering new sequence families and for comparing the user's sequence with the database of consensus sequences.ResultsWe describe the software named VisualRepbase and the associated database, which allow for displaying and analyzing all occurrences of transposable element families present in an annotated genome. VisualRepbase is a Java-based interface which can download selected occurrences of transposable elements, show the distribution of given families on the chromosome, and present the localization of these occurrences with regard to gene annotations and other families of transposable elements in Repbase. In addition, it has several features for saving the graphical representation of occurrences, saving all sequences in FASTA format, and searching and saving all annotated genes that are surrounded by these occurrences.ConclusionVisualRepbase is available as a downloadable version. It can be found at http://girinst.org/repbase/update/visual_repbase.html.
