[Biococoa-dev] strider and gck format

[Alexander Griekspoor]

Hi Koen,

Indeed hard-coding a path isn't very elegant ;-) I'm not sure whether  
we need the sequenceIOcontroller though.
I would let the app decide how to do the interface and obtain the  
file path/url, after that everything can be done in the reader/writer  
classes.
The reason is that 1) interfaces can be very different (i.e. metal or  
not), 2) implementations can be very different. An an example, in  
iRNAi i use the code that I included in previous emails, in EnzymeX 3  
I make use of the standard NSDocument routines. No need to do any  
panel at all, just subclassing the read/writeFileFromPath:ofType:  
methods, all the panel stuff is handled by NSDocument itself. It  
might even be nice to have one demo app use this approach and one the  
iRNAi type approach.
Cheers,
Alex
