MetaProteomeAnalyzer (MPA) is a scientific software for analyzing and visualizing metaproteomics (and also proteomics) data. The tool presents a MS/MS spectrum data processing application for protein identification in combination with an user-friendly interactive graphical interface. The metaproteomics data analysis software is developed in the Java programming language and provides various features for an user-defined querying of the results. In addition, MPA can also be executed on the command line (see below).
MPA Portable is a light-weight and stand-alone software for the identification of proteins and in-depth analysis of metaproteomics (and also proteomics) data. The MPA software currently supports the database search engines Comet, MS-GF+ and X!Tandem taking MGF spectrum files as input data. User-provided FASTA databases (preferably downloaded from UniProtKB) are formatted automatically.
Please note: MPA Portable can be run directly on your desktop PC or laptop and no separate installation is needed: just double-click the provided JAR file or use the provided batch file (see below on this page). Otherwise, you can use the command line interface (MetaProteomeAnalyzerCLI).
MPA can also be used via the command line, see MetaProteomeAnalyzerCLI for details.
It is also possible to import results in mzIdentML format which have been generated in other database search tools, see MzIdentML-Import for details.
The MPA metaproteomics software comes with the following key features:
Please download the latest version of mpa-portable-X.Y.Z.zip
(where X, Y and Z represent the current version of the software).
Before starting the MPA Portable version, please make sure that you have Java 1.8 installed. To check the currently installed java version, open a console/bash window and type:
java –version
If you haven't installed Java 1.8, please go directly to Java.com to download the latest Java version.
MPA Portable can installed directly as Miniconda package from the bioconda channel:
conda install mpa-portable -c bioconda
After downloading the zip file, simply unzip the file and use the provided script from the built folder, i.e. mpa-portable.bat for Windows or mpa-portable.sh for Linux (granting the access rights accordingly!).
You can also double-click on the JAR file, however this will give you no options to change the memory settings (see below).
Another possiblity is to use the command line directly:
java -jar mpa-portable-X.Y.Z.jar -XmxXXXXm
Note: -XmxXXXXm stands for maximum assigned memory (in megabytes of RAM)
