This scheme describes how to merge sequences and manipulate with its annotations.
First, the workflow reads sequence(s) from file(s). Then, marks the input sequences with the sequence name marker. After marking the sequences are grouped by the marker. Sequences with equal markers are merged into one sequence. Annotations are shifted using the position of the corresponding sequence at the merged sequence. And finally, the grouped data are written into file, specified by a user.

If you haven't used the workflow samples in UGENE before, look at the "How to Use Sample Workflows" section of the documentation.
