programme to predict amphipathic helices in a protein aminoacid sequence - (Feb/25/2008 )

Dear All

I have an amino acid sequence of a protein and I am interested in identifying potential amphipathic helices in the protein sequence, if any.

Can anybody suggest me any (reliable) programme to predict amphipathic helices in a protein aminoacid sequence? How can I access this programme?

Thanks in advance.
