Luis,
Thanks a lot!
I just realize that the xml file from TPP output is already run
through PeptideProphet with 0.05 cutoff.
I will try to rerun the xtandem along to see how it works.
Best,

Hi Kristian,
Also, 4.2.1 contained many bug fixes. I'm not sure if this would have been
addressed, but it's always most efficient for us if you can try to replicate
the issue on the latest version.

Hi Oded,
You are correct; this was a feature with a very old version of the pepXML
display that isn't currently active. The current viewer is strictly
read-only, so far. This hasn't been a very high priority so far as
xinteract and the prophets do the most common filtering (probabilities), but

I have had some problems before if any of the pep.xml files had identical
names. Renaming them (and paths/names within the files) solved that
problem.

Hi,
Long time ago there was an option to save a subset of a pepXML (for
example only peptides with ratio >2) to a new pepXML file through the
GUI but I haven't seen it for a while. Is it still possible to it with
the latest TPP though the GUI (or by using the command line somehow).
Thanks for any
I'm using TPP 4.2.0 to analyze cleavable ICAT data from an LCQ. When
all replicates are done, I have 120 seperate .pep.xml files to combine
and analyze. With earlier versions of TPP (i.e. 3.4) I could analyze
them all at once with Xinteract, but with 4.2 the operation simply
aborts and fails wit
Hi Angel,
I have setup some proteomics tools running on parallel on a Linux
cluster here at the Beckman Research Institute of City of Hope Medical
Centre.
I am not sure what you are looking for exactly: student, postdocs,
collaboration or consultation.

Hello Ping,
Yes, please make sure you run xinteract with the -p0 (zero, not "O")
option. QualScore uses those to model the "bad" spectra.

Luis,
I finally got my PepXMLViewer working. I opened the file, and there is
no entries with exact zero
probability. But there are tons of entries with ~0.05 probability.
Does that matter? Or QualScore
only considers that zero probability as bad spectra?
The data is LTQ data, and first is search
Mattias,
I just checked in the Xpress changes to trunk (revision 4331). Give it
a shot and let me know if there's any problems.
There was mention of 15N support in ASAPRatio in the 4.2 announcement.
After doing more snooping, the following check-in added support for
initializing AA masses vi
Hi Matthias,
[Looks like some other folks might be able to help you out directly;
take the below with a grain of salt]
Most of the folks here work with LC not GC MS. However, the existing
software for extracting LCMS data should at least get you started
towards your own. I would start with
Hi Mattias,
To get started with Xcalibur, you might want to look at the "XDK" for
examples.
But I do think it will be easier if you can just use and/or adapt existing
tools. I know that Matt from the ProteoWizard (PWIZ) project (including in
the TPP) has been interested in parsing chromatogram d
The great thing about TPP, of course, is that it's open source. So, you've
already got source code and MSVC build files for readw, which shows you
exactly how to use the Thermo DLLs.
After that, well, Google is your friend!
Begin here:
https://sashimi.svn.sourceforge.net/svnroot/sashimi/trunk
ProteoWizard's msconvert will almost work for this. If you give me an
example RAW file I can fix it up rather quickly. ReAdW isn't close to
being able to support this, not least because mzXML doesn't support
chromatograms (and it's also entirely about mass spectra). I have tested
msconvert on

Dear all
I am an absolute newbie and I am not sure if I came to the right
place... well, here's my question:
I am looking for a tool that extracts chromatogram data from XCalibur
*.raw files and converts them into a format that is readable by other
software (e.g. Matlab or Octave). My *.raw file
Any updates concerning this problem?

Hi,
I'm performing TPP analysis for my 14N/15N metabolic labeling
