I'm not SELLING this program, I just thought you might find it useful to know 
about!  It is designed primarily to estimate a number of parameters of 
synthetic peptides - ease of synthesis, prediciting difficult sequences, 
predictive algorithms for structure, predictive mass spec fragmentation, 
predictive HPLC compared to any standard you might use, digestion fragemts 
from enzymatic and chemical digest - and, yes, elemental composition as a 
small part of the amino acid analysis predictions.  YOU might have the skills 
and time to sit and write programs or macros in spreadsheets, some of us have 
to rely on others to do this for us, and I think that for the relatively small 
sum of US$89 this little program does a good job!

Anyone who's interested can contact Coshisoft on:
