GalaxyP - PeptideShaker
Description
Perform protein identification combining numerous search engines (using SearchGUI) followed by peptide and protein inference with PeptideShaker.
Includes tool wrappers for FastaCLI, IdentificationParametersCLI, SearchGUI and PeptideShaker.
FastaCLI adds decoy sequences to any fasta file.
The Identification Parameters tool allows to create a parameters (par) file which can be (re)used later to parameterize SearchGUI or PeptideShaker.
The SearchGUI tool takes any number of mgf files and performs searches on these. It creates a large zip archive with all search results, the original database and spectra.
This can then be fed to the PeptideShaker tool which merges the results and performs peptide and protein inference.
General Requirements
To avoid out of memory errors you may need to set the maximum heapspace for java processes if the default is too small for the data you are going to process (4gb for SearchGUI, 1GB for PeptideShaker).
For example, to set this in your shell:
export _JAVA_OPTIONS='-Xmx8192m'
On some systems you may also need to adjust the amount of memory available for class definitions in addition to the maximum heapspace. For example:
export _JAVA_OPTIONS='-Xmx8192m -XX:MaxPermSize=1024m'
It is also possible to set this on a per tool basis using advanced features of the galaxy job config system.
MSAmanda on linux
Running MS Amanda on Linux requires that you have Mono installed. Mono 3.2.1 or newer is required. If you install via the toolshed Mono should be installed automatically, however if this does not work you can install it manually.
On ubuntu Mono can be installed as follows
sudo apt-get install mono-runtime
sudo apt-get install libmono-system-core4.0-cil
For more help on installing Mono please see http://www.mono-project.com/download.
Note
- Requires Galaxy release v20.01 or later.
