Hi,

We have realized some inconsistency in the intensitites reported by
Libra  on TPP (v4.0 JETSTREAM rev 2, Build 200810230133 (linux) ): The
intensities are pretty much systematically off (lower?) compared to
the "real" intensities that can be seen in the raw data (profile raw
data or mzXML centroided raw files or .dta exported scans from the
mzXML).

I made a couple of copy-screen to explain what I mean more in detail.
Here is the link to find the ppt file:

http://rapidshare.com/files/264430463/Libra_issue.ppt.html

Note that ALL the Libra intensities reported (113, 114, 115...) are
off compared to what is reported in the dta file (compare numbers on
last slide and first slide)

Can you please give some feedback on this strange behavior? Where does
Libra fetch the reported intensities from? Is it from the mzXML files
or from the dta files? Are the intensities recomputed by any way by
LIbra?

Thanks in advance,

Ludovic
