>seqA
                        ATCACTA
                        >seqA
                        CACTG
                        >seqB
                        ATCACTA
                        

ove duplicated IDs:

                    Only the first ID is used, all others are ignored (not written to the output)
                    After removing duplicated IDs, the output for the above example would be:
                    >seqA
                    ATCACTA
                    >seqB
                    CACTG
                    

2) Detect and remove duplicated sequences If this checkbox is activated, all entries with the same sequence are eliminated The result for the above example would be:

                            >seqA
                            ATCACTA
                        

3) Detect and remove duplicated sequences & generate a new ID by pasting the sequence IDs that have the same sequence (if this checkbox is activated → launch with mode RDG) If the "paste names" checkbox is activated, the output would be:

                            >seqA=seqB
                            ATCACTA
                        

4) Manipulate the sequences names (eliminate a certain string) The UCSC table browser allows to obtain 3' UTR sequences which are needed when searching for microRNA target genes. However the output files have the following format:
