[Bioperl-l] Bug or special design of the 'length' method for Bio::Seq ?

[Tao Zhu]

Hi,everyone
Suppose a protein sequence like:

 >Protein
MAASEHRCVGCGFRVKSLF*

Do you think the length of such sequence is 19 or 20? In my opinion, the 
star "*" is only a terminal symbol of a protein sequence, so it 
shouldn't be counted into protein length. But in fact the "length" 
method of Bio::Seq results in length of 20.
