Tandem repeat search tools performance for the Arabidopsis thaliana genome

In eukaryotic genomes, tandem repeats represent two or more adjacent copies of pattern nucleotides. They are the most principal cause of various genetic diseases. So, it's very important to locate and define them. During the last decade, many tools (TRF (Tandem Repeats Finder), Mreps, Sputnik, ATRHunter equicktandem, etandem...) have been developed to search tandem repeats in DNA sequences. However, search algorithm results are various. It is not easy to choose appropriate parameters settings for each one. In addition, when varying the parameter settings for a particular tool, the user can found different results. In this paper, we present uses of four tools for search tandem repeats and we investigate Arabidopsis thaliana's sequence to compare the software's performance.
