, that may not exist for newly sequenced genomes.  ...  Results: We have developed a software tool called WindowMasker (WM) that identifies and masks highly repetitive DNA sequences in a genome, using only the sequence of the genome itself.  ...  We thank Victor Sapojnikov for assistance in testing both RM and WM and for guidance in enhancing the input/ output options so that WM could be used in NCBI's genome pipeline.  ...

Red: an intelligent, rapid, accurate tool for detecting repeats de-novo on the genomic scale

Hani Z. Girgis
2015 BMC Bioinformatics  
With rapid advancements in technology, the sequences of thousands of species' genomes are becoming available. Within the sequences are repeats that comprise significant portions of genomes.  ...  As species-specific elements, repeats in newly sequenced genomes are likely to be unknown. Therefore, annotating newly sequenced genomes requires tools to discover repeats de-novo.  ...  Many thanks to Virginia LoCastro for her invaluable comments on my writing of this manuscript. The author wishes to thank David Landsman, Alex Astashyn, and David Managadze for useful discussions.  ...

A novel genome-scale repeat finder geared towards transposons

Xuehui Li, Tamer Kahveci, A. Mark Settles
2007 Computer applications in the biosciences : CABIOS  
Our experiments on the Arabidopsis and rice genomes show that Greedier identifies approximately twice as many transposon bases as those found by cross_match and WindowMasker.  ...  Moreover, Greedier masks far fewer false positive bases than either cross_match or WindowMasker. In addition to masking repeats, Greedier also reports potential nested transposon structures.  ...  WindowMasker ( masker/) is a de novo repeat finder that was developed specifically to mask large sequence databases.  ...

2011 Genome Biology and Evolution  
We have developed a bioinformatics pipeline for the comparative evolutionary analysis of Ensembl genomes and have used it to analyze the introns of the five available teleost fish genomes.  ...  We show our pipeline to be a powerful tool for revealing variation between genomes that may otherwise be overlooked with simple summary statistics.  ...  Casey Bergman, who advised on repeat sequence analysis; and to Dr. Andrew Davidson for providing input on the draft manuscript.  ...
