        This tool uses output from DANTE annotation pipeline to identify full length LTR
        transposable elements. Output is in the GFF3 format and include annotation of
        5' and 3' Long Terminal Repeats, Target Site Duplication (TSD) and primer binding site (PBS).

        All identified elements contains set of protein domains as defined in
        REXdb_.Based on the results of detection of structural features,
        elements falls into five categories:

        - elements with domains, 5'LTR, 3'LTR, TSD and PBS - rank DLTP
        - elements with domains, 5'LTR, 3'LTR and PBS (TSD was not found) rank DLP
        - elements with domains, 5' LTR, 3'LTR, TSD (PBS was not found) - rank DTL
        - elements with protein domains, 5'LTR and 3'LTR (PBS and LDS were not found)  - rank DL
        - elements as cluster of proteins domains with same classification, no LTRs - rank D
