Hi Sunny Bao,

Here is a description of one of the possible solutions for your:

1) Open your sequence in UGENE ( http://ugene.unipro.ru ). Just run
UGENE and use "Open" button or menu.

2) Select "Actions->Analyze->Find repeats" from the main menu

3) Select the repeats parameters: size/identity/distance etc...

4) Push start button and see the repeated regions as annotations
(highlighted regions) to the sequence.

Hope it helps,
Mike.
