Excel 4.0, Fast Fourier HELP!!!

[mspizuco@xxxxxxxxxxxxx (Matthew Paul Spizuco)]

	Greetings,
	
	This distress call goes out to anyone who has successfully used 
the Fast Fourier function of the PC-Excel 4.0 Analysis Add-on.  I've been 
trying to use it for shape analysis of cetothere and baleen whale ear 
bones, but the manual is useless, the Help files are useless, and the 
service reps at Microsoft don't know what to do with it.  Great.
	Here's is my situation.  I have 49 near-mint (sorry, comic
collecting term) bullae whose individual outlines have been digitized
into sets of several hundred X-Y co-ordinates. According to Excel, these 
co-ordinates have to be entered within a single collumn in an X+Yi 
format.  It took several calls to Microsoft to discover that "i" 
represents an imaginary valve. Very helpful.  So the co-ordinates have 
been added and now I have several hundred single values.  I run this 
column through FF and receive several hundred X+Yi values with absolutely 
no explanation as to what they mean. Reading articles and texts involving 
Fast Fourier has not provided insight into how data should be inputed or 
how to understand the output.  It's times like this that make it 
difficult to argue in favor of PCs over Macs.
	Again, I would love help from anyone who has experience with this 
program.  If you can suggest another Fast Fourier application, with very 
good documentation and a price that won't hurt a struggling grad student, 
I would be interested. Thank you.
