[Biopython] Amphipathic index module

[Ankesh Thakur]

Dear friends,

I am looking for a module to calculate the amphipathic index (AI) of amino
acid sequence. The amphipathic index is defined by conette et al (1987). In
order to calculate  AI, it is required to integrate discrete fourier power
sectrum. Please let me know if there is any module available for easy
calculation of AI or do I have to write it.

Regards,
Ankesh
