We developed a software named Repeat Locator (RepLoc), which quantifies the sequence repetitiveness based on weighted k-mer coverage. The repetitiveness map (Rmap) generated by RepLoc can be used to determine all repetitive sequences in the genome. The potential applications of this method include: de novo repeat detection (both common repeats and segmental duplications), genome structure and genome mappability analysis, etc.

The workflow of RepLoc:
