[Biojava-l] removeGap problem with SimpleGappedSequence

[mark.schreiber at group.novartis.com]

Sounds like a pretty sensible suggestion. Can anyone think of why this 
might not be a 'good idea'?

If not, i'll add it to the list of things to fix :)

Hi,

'createGappedDNASequence' would solve the problem in this example but in 
fact it was just an example, in the real application the sequences are not 
always created with DNATools and a lot of time we create a 
SimpleGappedSequence from a Sequence.
I was wondering if it would be possible to let 
SimpleGappedSequence(sequence) create a view that immediately contains the 
gaps available in the original sequence.  With that view it would be 
possible to remove the gaps in the original sequence and add/remove new 
gaps.

David
