I'm not exactly sure what you mean here - are you asking how to call a 
class method?  These are just defined with a "+" instead of a "-" in 
the header.  So you would just send a message to the class itself (no 
need to allocate it or anything).  Like:

BCNucleotide *myG = [BCNucleotide gNucleotide];

The BCNucleotide class method would either allocate a new G instance, 
or return one it already made.

Sorry I haven't been participating much in the design discussions - I'm 
trying to write a dissertation here!  I am hoping to have lots of time 
for coding in a couple of months.

- Jim
