Help with LINES SINES and Genomic elements - (Jan/25/2008 )

Hi friends :-)

I am working with the LINES and SINES and GENOMIC ELEMENTS, the repetitive elements of the genome and the genome is Human Genome...

Is there any repositories or databases that give information about them???
Is there any program that identifies them in the genome???

Waiting for your reply...
Thanks in advance!!!

to identify repeats you can use repeatmasker (http://www.repeatmasker.org/), this is also present as a track in the UCSC genome browser
