Classifies transposable elements (TEs) by searching for structural features and similarities. PASTEC, developed in the REPET package, allows to classify TEs automatically to order level, for all nine orders of autonomous TEs defined in Wicker’s classification plus three orders of non-autonomous TEs (LARD, TRIM and MITE). The software is also designed to filter out false-positive repeated sequences identified by de novo approaches and to classify and recognize incomplete and potentially chimeric TEs.
