All of the TPP is released under the LGPL license. Some other programs (converters) have different licences.

Version control

This project is hosted at sourceforge ([1]) under the "sashimi" project, using SVN.

You'll need to be a project developer: register at SourceForge and contact one of the main Sashimi developers.

XML Parsing libraries

[edit]

perl

  • xml tree
[edit]

c++

  • A. Keller's "tag" system:

All Parser programs (children of Parser.cxx) parse pepXML and protXML with the constrain that all text be enclosed within a 'tag' such as the following example: 

<mytag name="akeller"><email address="akeller@systemsbiology.org/></mytag>

NOT ACCEPTABLE are files with text outside of a bracket tag enclosure, such as 'akeller' in the following illegal example: 

<illegaltag>akeller</illegaltag>
  • J. Tasman code


[edit]

System Requirements

[edit]

Webserver

Webserver with access to data directories. See configuration section below. Apache support is the default configuration and is installed and configured on port 1441 automatically as part of the current cygwin installation. IIS on windows is no longer a supported configuration.

[edit]

XSLT Processor

The TPP currently relies on an "xsl transform" processor for manipulating XML data.

  1. One such program, xsltproc, is usually distributed with Linux so you most likely already have it. It should reside in the /usr/bin/ directory. If it is not already on your computer, first try to install it via the standard package system for your distribution, or the cygwin installer for cygwin. Otherwise you can download it for free at: http://xmlsoft.org/XSLT/downloads.html
  2. Another freely available XSLT processor, Xalan, will also work fine with ProteinProphet. If you use it, just make sure it is installed in a directory already on the library path, or else set the LD_LIBRARY_PATH variable to include its location on the webserver: 
Add LD_LIBRARY_PATH files to /etc/ld.so.conf
Then type: ldconfig -v

The viewing of large xml files is sometimes slow. We are hoping to optimize the stylesheets in the future, and in some cases, bypass XSLT altogether.

[edit]

Libraries

  • expat-2.0.0 (copied to svn tree)
  • boost 1.32
  • xerces (version?)

You will need to install the following C libraries. These libraries are very common on linux distributions. Make sure that you do not already have them before trying to install. If you do need to install, first try to use the standard package system (e.g. RPMs for Fedora linux , cygwin installer for cygwin-- see below, etc.) If you cannot install them via the normal package system for your distribution, go to their website and download directly.

  • libgd www.boutell.com/gd
  • libpng www.libpng.org
  • zlib www.gzip.org/zlib

Windows users should get this by using the Cygwin installer (www.cygwin.com). Make sure to get the devel packages, in order to have the required .h files.

[edit]

Building from source

[edit]

Configuration

On TPP:Documentation you can see other guides for building on specific systems.

Skip ahead to Compilation for a Cygwin build, the following is for Linux only. Note that we distribute precompiled binaries in a complete custom cygwin installation.

[edit]

Edit the src/Makefile.incl file

Set the TPP_ROOT variable to the directory where you want to install the TPP. Include the trailing '/' when setting the path, e.g.: 

TPP_ROOT=/usr/local/tpp/

Set the TPP_WEB variable to the webserver root relative alias to the TPP. Include the trailing '/' when setting the path, e.g.: 

TPP_WEB=/tpp/

WARNING: To avoid problems during the installation 'you MUST include the trailing '/' when setting the above two paths'.

  1. Set the XSLT_PROC to the path of the xsltproc executable on your system 
XSLT_PROC=/usr/bin/xsltproc

In the src directory, type 'make configure' (once again, DON'T DO THIS for Windows/Cygwin!!!)

[edit]

Compilation

[edit]

Linux

In the src directory: type 'make all' to compile binaries

[edit]

Windows/Cygwin

In the src directory: type 'make windows' to compile binaries
[edit]

Installation

[edit]

Linux

In the src directory: type 'make install' to install all the binaries

The TPP will be installed in the following directory structure by default:

/usr/local/tpp
TPP root directory
/usr/local/tpp/cgi-bin
CGI-BIN for tpp, contains all web served executables
/usr/local/tpp/bin 
binary directory
/usr/local/tpp/html 
contains all non-executable web served objects
/usr/local/tpp/etc 
contains miscelaneous configuration files
/usr/local/tpp/schema
contains all XML schema files
[edit]

Windows/Cygwin

In the src directory: type 'make install-windows' to install all the binaries



[edit]

Webserver Configuration

Ideally, all data directories should be cross mounted under the webserver root. Webserver should have SSI (server side includes) turned on. If it is not already, you can activate the Web Server SSI (Server Side Includes)

[edit]

Activating SSI on Linux

Modify the /etc/httpd.conf file:

In the document root <Directory> section, add +Includes to the end of already existing Options line: 

 Options +Includes

Uncomment or add in the mod_mime.c section: 

AddType text/html .shtml
AddHandler server-parsed  .shtml

Then restart web server: /etc/rc.d/init.d/httpd restart


[edit]

Webserver Root

The environment variable WEBSERVER_ROOT must be set for the program user(s) as well as the webserver. The WEBSERVER_ROOT should point to the webserver's document root directory (e.g. /home/httpd/html on linux/apache, or ??? on windows/IIS ).

[edit]

Apache specific webserver configuration

Configure the webserver:

Add the appropriate web paths to the TPP as described below. If you are using the Apache http server, edit the active 'httpd.conf' file. Add the following Alias and ScriptAlias Directives as described below. Be sure to link to the appropriate tpp-version number. 

#
# ISB-Tools Trans Proteomic Pipeline directives
#


Alias /tpp/html "/usr/local/tpp/html"

Running the TPP

[edit]

Overview

Specific instructions are geared towards command-line usage. Note that the web-base GUI is a very convenient way to do these steps.

[edit]

Conversion of raw spectroscopy data to mzXML format

[edit]

Assigning peptide sequences to spectra (using a search engine)

[edit]

Converting search engine results to pepXML format

Analysis programs begin with a pepXML-format file called 'summary.xml', containing the peptides identified by the search engine.


  • For SEQUEST results, you must specify the sequest.params file used for the search:

In directory with summary.html and summary.mzXML (as well as the SEQUEST results .tgz or subdirectory), type: 

Sequest2XML summary.html -Psequest.params
  • For Mascot results, you must specify the database used for search:

In the directory with summary.dat and summary.mzXML, type: 

Mascot2XML summary.dat -D/full/path/database

You can view the search results by opening the 'summary.xml' file in your browser.

[edit]

Processing peptide data with the pipeline (using xinteract)

Next, you can run xinteract to apply all or some parts of the pipeline. Type 'xinteract' with no arguments for usage instructions. You can also convert and run the pipeline in one step. See xinterct instructions for details.


[edit]

Example

To run the pipeline manually, starting with file1.xml and file2.xml:

  1. Combine together data from 2 files:
  2. InteractParser interact.xml file1.xml file2.xml

Peptide Results can be viewed at any point along the analysis by opening the interact.shtml link.

  1. Run PeptideProphet 
PeptideProphetParser interact.xml
  1. Run XPRESS 
XPressPeptideParser interact.xml
  1. Run ASAPRatio 
ASAPRatioPeptideParser interact.xml
  1. Go into database to retrieve all proteins corresponding to identified peptides 
RefreshParser interact.xml /full/path/database
  1. ProteinProphet 
ProteinProphet.pl interact.xml interact-prot.shtml XML_INPUT

From this point on, all analysis is on the output from ProteinProphet: interact-prot.xml Protein Results can be viewed at any point along the analysis by opening the interact-prot.shtml link.

  1. XPRESS Protein 
XPressProteinParser interact-prot.xml
  1. ASAPRatio Protein 
ASAPRatioProteinRatioParser interact-prot.xml
  1. ASAPRatio Pvalue 
ASAPRatioPvalueParser interact-prot.xml
