[Biojava-l] question about ambiguous symbols

[dion.whitehead at uni-bielefeld.de]

Hello,

I am having a frustrating time with attempting to read in rna sequences. 
They contain the 'N' symbol which is a standard ambiguity symbol, but the 
code trips up on this every time, saying its not a recognized symbol in the 
alphabet. Do I have to specify it myself?

Thanks, and keep up the good work,
dion
