Re: [Psidev-ms-dev] binaryArrayData lengths

[Marc S. <st...@in...>]

Hi all,

i like that idea of being able to annotate a small subset of the peaks 
in a spectrum.
This is e.g. needed when assigning ion types for MS/MS: b1, b2, ..., y1, 
y2, ..., y7-H2O, ...
Most of the peaks are simply noise and so only a minority of peaks will 
have an annotation.
Using a full-sized array would be possible, but a waste of space.
In my opinion, there should be a recommended way to do such a thing. 
What do you suggest?

Before i forget: Is it possible to annotate peaks with strings? 
Otherwise we would have to use some kind of dictionary to assign ion 
type an integer index.
