Abstract
Motivation: Tandem repeats are repetitive elements in DNA sequences, which are assumed to be an important cause of genomic instability in biological science. It has implications in human genetic stability, human gene mapping, forensic DNA fingerprinting analysis and other DNA complex structures analysis. Published literature is prolific on algorithmic techniques for identification of tandem repeats but almost non-existent on their comparative evaluations. Results: Experimentation with many available algorithms and evaluation of their performances led to narrowing down focus onto five competitive software tools. These tools are analyzed as to their efficiency, accuracy, robustness, flexibility, and user interface capability.
