[Biococoa-dev] BCSequenceCluster

[Charles Parnot]

At this point, given that I don't know that much about the fine  
details of sequence clusters and sequence groups, could you, Peter,  
take some time to explain exactly what the concept is, and also maybe  
come up with some examples of what it can be used for and how a user  
of the framework would want to use it. This way, we can define a  
header that does the job, and then worry about the implementation. In  
fact, I should have asked that question in the first place instead of  
pretending I understood what it was all about!

Sorry maybe this is a quite wide question. We don't have to go too  
deep at this point, as we merely want some I/O to work. However, in  
'I/O', there is 'O' for output, so the question is: after loading a  
sequence from disk, what information will the user want to retrieve?  
Or will she just want to perform some operations on the sequence  
group and then move on?

cheers,

charles
