←Older revision | Newer revision→

Trans-Proteomic Pipeline (TPP) software, release 6.0.0 is a major release of TPP that contains new features, improvements, and fixes to 5.2.0. The software is available for Windows as well as Linux (and unofficially) for OSX from all the usual locations (please see the section below, "Getting the software"). Most users are recommended to use the Windows installer, which installs and configures the TPP and other required software (such as a web server). For advanced users who need to customize the TPP, or for those who run on Linux or OS X, you can download the source code. Again, most users don't need build from source, and should use the Windows installer.

For installation help, please see TPP:5.2_Installation (same as for 6.0.0)

Major Changes

Added new TPP "Landing" page for local installation
- Mostly links to local TPP interfaces, external resources, release notes, and related info
- becomes new default location of TPP link (instead of Petunia)

Added support for fetching remote spectra via their Universal Spectrum Identifier (USI) in Lorikeet
- Enables interactive examination and interrogation of spectra stored in public repositories (only PeptideAtlas so far)
- Can be displayed standalone or butterfly-style for comparison against currently loaded spectrum

Major updates to ASAPRatio peptide UI:
- Add button to list IDs info in a table and overlay onto chromatogram (calls qsir via AJAX/json)
  - Added qsir utility to extract all CIDs info within specified scan and m/z ranges
- Enable mouse drag for selection of scan range and background (with toggle)
- Simultaneous adjustment of light+heavy scan ranges by holding down <shift> while dragging mouse
- Highlight input elements that have changes
- Add toggle to display relative vs absolute y-scale ranges
- Added 'X' to zero out background
- Cease using gnuplot/png images and instead use flot.js
- New L&F

Major revamp of ASAPRatio protein UI:
- New page layout: single table with collapsible peptide sections
- Added more obvious "accepted" status for peptides, peaks, spectra
- Added NTT and mapping uniqueness flags to peptide bar
- Added background color quant scale
- Added link to MADCAPS
- Fixed links to PepXMLViewer; Lorikeet; TPP Models
- Added pop-up messages window
- Fixed memory overrun when building mods in spectrum links

New tool fixPepXMLScan that can update (to a new file - no overwriting) pepXML files that have scan indexes that do not match the mzML files.

New tool MikesMagicalMzMLShrinker to shrink mzML files.
- Its most basic functions remove white space and truncate user-defined identifier tags to a minimal size.
- More advanced features adds MS-Numpress compression to the files. No matter what, the data are zlib compressed (if they were not zlib compressed previously).
- Only works with mzML files. Not for mzXML. Not for mzML.gz. However, for mzML.gz, you can gunzip it, magically shrink it, then gzip it back up.

New utility msnExtract for extracting fragment spectra

New tool PepExtract
- simple single command tool to run comet, PeptideProphet, iProphet, PTMProphet and then export results as xls
- tpp/bin and tpp/cgi-bin have to be in the PATH

New tool SPACEPro to quantify and evaluate digestion efficiency at the PSM, peptide, and protein levels.

New utility StPeter2Matrix for combining multiple StPeter analyzed ProtXML files into a single 2-dimension data matrix of protein abundances.
- The application reconciles differences in protein grouping that occur among the different ProtXML files, and error rates (at least for now) are controlled using a single ProteinProphet analysis of all the combined datasets.

New Tools: mzTrace, rtExtract, DidIScanThat, DIALib-QC (v1.2), QuanticProteinParser

MADCAPS replaces old comet-fastadb.cgi as the default protein sequence viewer in TPP
- A link to the old viewer is still provided in MADCAPS

New tool PPSX for Peptide-Protein Sequence eXploration. Mostly a front-end to promast

New tool ptm2plot -- extracts PTM peptides and site probs from pepXML and creates files for visualizing in ploTPP

New tool quiddist to query peptide ID info and overlay it onto DidIScanThat output
- takes in extra (optional) list of pepXML files
- Launch this tool from Petunia instead of DidIScanThat
- Show results in TPPcel table, with links to PepXMLViewer for each scan with an ID

New tool TPPcel to visualize sets of similar tables in TPP
- Can load data via a few flavors of json, TSV (first 2 columns only), name=value lines, and various params files
- Can display data from multiple source files side by side to allow comparison of values, including ability to see only rows with non-equal values
- Simple one-click bar chart mechanism
- Experiment labels used in table headers are user-editable
- Able to receive "postMessages" from other TPP tools which trigger auto-loading of a new file
- Ability to Copy-Table-To-Buffer-As-TSV
- Includes js FileBrowser for ease of data loading

New Unimod helper utility to view and add Unimod mass mods via pop-up widget
- list can be multiply filtered by user-specified string(s)
- user chooses from potential sites
- value of input element is set to conform to parameters format (comet/msfragger, kojak, tandem) and field type
- highlights associated input text field
- link to Unimod entry
- Added custom unimod.json to enable above (generated via local script from unimod xml export)
- Used in Petunia (comet etc params) and Lorikeet (custom user peptide)

New TPPFileChooser utility to browse/choose files or directories to view/load via pop-up widget
- Added to Pep3D, ploTPP, PPSX, PepXMLViewer, ProtXMLViewer
- Able to sort/filter by name, size, and date
- Keeps directory history
- Can be repositioned via mouse-drag
- Uses new cgi to serve directory listing via json

New RACI library (Random Access Compressed Ifstream)
- This small library (libraci in TPP) can be used in place of pwiz::util::random_access_compressed_ifstream
- It is actually the same-ish code, but deboosted in favor of STL, and without the need to drag the entire ProteoWizard with it.
- Simple, lightweight, and you can still read pep.xml.gz files

New NeoMzMLParser API -- a new, object API for reading and writing mzML files. Also supports scan-by-scan iterative reading or writing.
New NeoPepXMLParser API -- a new C++ API for reading and writing PepXML files. This is intended to *eventually* replace the libpepxml currently in TPP.
New NeoProtXMLParser API -- a new C++ API for reading and writing ProtXML files. This is intended to *eventually* replace the libprotxml currently in the TPP.

  - Tools that use one, the other, or both can then link one, the other, or both as needed, instead of forcing every tiny little script to link everything all the time.
- change uninitialized values from -1 to a much smaller number (iRT values can be negative.)
- only lop off everything past the last '_' when in DISCO mode, in regular mode keep the run names unaltered

SpectraST
- Fix MSP import of new NIST HCD libraries due to different format in mods, fragmentation, etc. HCD collision energy now part of spectrum's identity, so that spectra of same peptide ion but of different CEs will not be considered replicates.
- Fix bug writing create mode indiscriminately to Spec= field

StPeter
- Added new parameter to set minimum probability threshold regardless of FDR.
- Added peptide-level normalized spectral index score (per Henry Lam's request)
- clarifying output to the user.
- Fixed rounding bug when representing modification masses on peptides.

tpp2mzid
- New interface to specify preferred mzID version (for PRIDE compatibility)
- add new content to the mzID output
- Updating software to work with the newer mzIMLTools API
- bugfixes and improvements for PTMProphet to mzID.

tpp models
- Update to new L&F
- Use new common tpp.css (also enables sticky table headers!)
- Added support for multiple PeptideProphet models in same file (e.g. for XL analysis); also added score overlay of massdiff, isomassdiff, ntt, nmc, etc
- Add button to toggle 1% Zoom in MASSD models
- Handle new matchedions model
- Also plot sum of pos+neg models for each charge state
- Display all PTMProphet run options
- Fix bug in parsing certain PTMProphet models; do not capture data points with value = zero; enable auto-tickmarks for MASSDIFF models (which can now be open search)
- Fix PTMProphet sens/err models and table

XPRESS peptide interface:
- Added LabelFree option, which displays (single) chromatogram, fit, and parameters
  - "View" only; no curation yet
- Also added marker at scan number of CID, labeled and label-free
- Updated to new L&F
- Added pop-up messages window
- Adjust link target window names in protein page

XPRESS protein interface:
- New L&F
- Use AJAX call when updating protein ratio
- Update links to point to pepXML models page, viewer, Lorikeet
- Added option to xpress-prophet-update.cgi to return html portion (not entire page)
- Fix link from ProtXMLViewer

HardKlor
- Updated to support Ion Mobility
- use spectrum member variable to boost speed in multi-threaded setting where reallocs add up

MSToolkit
- Updated to support Ion Mobility (TIMS_TOF)
- mzParser deal with Precursors in mzML to store isolation window info
- Improved memory management with fewer reallocations to improve performance in multi-threaded applications

cramp
- fix case where scan number was being used as a scan index

tpp pwiz
- allow pwiz to process more, differently encoded, files

Greatly increase protein header size to handle PEFF headers in various components

Miscellaneous

Make usage statements somewhat more readable (esp. xinteract)

Standardize progress bar across various TPP components

New ISB-inspired wait "spinner". Added so far to ASAPRatio, Pep3D, and PPSX

comet params: Place full path to PSI-MOD.obo file, now in TPP distro

PWIZ Updated to compile on newer versions of gcc in msys2 mingw64 with pthreads

More descriptive error messages and feedback in various tools

Fix various memory leaks, and clean up of old/commented out code

Removed antique TPP model rendering utilities, old (pre-Lorikeet) plot-msms.cgi, and all references to them

CPAN perl modules Statistics::R, Statistics::Regression, XML::Twig added/required

Known Issues

promast calculates NTT for Trypsin only -- more enzyme support forthcoming
promast does not consider flanking SAAVs when calculating optimal NTT
Need to add more instruments to cvParams detection in mzParser
