Re: [Psidev-ms-dev] Smaller files

[Matt C. <mat...@va...>]

Hi Rune, mzML has both of these capabilities. With separate binary 
arrays (like mzXML 3.0 theoretically supports but so far is rare in the 
wild), the m/z array can be 64 and the intensity array can be 32, which 
is most likely to fit current instrument capabilities. Also, 
chromatogram time values probably don't need 64 bit either. SPC's 
converter tools support writing and reading compressed mzML last time I 
checked.
