Alright Saqib,

Robert is right that you should try fft in perl if you don't want to
learn Python.

But as I understand it, you want to read in this file, fft it, and
write the fft to a file using only numarray.  Attached is a script
that does that.  Most of the script is just low-level file io to avoid
having to install scipy to read and write the arrays.

Hope this helps,

Ryan
