[Biojava-l] anger error

[Ben Good]

Hi,

 Trying to implement this bit from biojava in anger ("How do count the 
residues in a sequence").

Count counts = new IndexedCount ((FiniteAlphabet)seq.getAlphabet());
                                        //iterate through the Symbols in seq
                                                for (Iterator i = seq.iterator(); 
i.hasNext();){
                                                AtomicSymbol sym = 
(AtomicSymbol)i.next();
                                                counts.increaseCount (sym,1.0);
                                                }
It compiles but gives a class cast exception when I try to run it.  
Won't accept (AtomicSymbol)i.next();

It seems that seq.iterator() returns an iterator over Symbols and not 
AtomicSymbols?

any ideas?

thanks
-Ben
