cdna

[Danielle et jean Thierry-Mieg]

sorry
there is a rigidity in the display code
you cannot do that

what you want to do is
have a model

?Sequence DNA UNIQUE ?DNA UNIQUE Int
          cDNA


and then 2 subclasses

Class cDNA
is_a_subclass_of Sequence
Filter cDNA

Class otherSequence
is_a_subclass_of Sequence
Filter "NOT cDNA"
