The MarVis-Suite: Marker Visualization, Filtering, Clustering, and Functional Analysis



The MarVis-Suite (Marker Visualization) is a toolbox for interactive ranking, filtering, combination, clustering, visualization, and functional analysis of data sets containing intensity-based profile vectors (data set features or marker candidates), as obtained e.g. from mass spectrometry (MS), microarray, or RNA-seq experiments. The clustering algorithm is based on a realization of one-dimensional self-organizing maps (1D-SOMs). Additionally, the MarVis-Suite includes specialized functions for analysis of MS data in the context of non-targeted metabolomics studies, such as adduct and isotope correction, molecular formula calculation, and pathway reconstruction based on accurate masses.

Within the MarVis-Suite framework, the MarVis-Filter interface provides functions for import, preprocessing, filtering, and combination of raw data files, while the MarVis-Cluster interface was designed for high-level visualization and cluster analysis. The MarVis-Pathway interface is used for functional annotation of filtered/combined (cross-omics) data sets or selected clusters in the context of reference or organism-specific pathway maps. For statistical analysis of combined data sets from different omics platforms, MarVis-Pathway provides an extensive framework for (Gene/Metabolite) Set Enrichment Analysis and meta-analysis. Within the MarVis-Suite, selected data can be easily exchanged between the different interfaces. Nonetheless, the interfaces can also be used as independent tools.

Download section


MarVis-Suite 2.0: MarVis-Filter, MarVis-Cluster, and MarVis-Pathway (2014)


Currently, the MarVis-Suite 2.0 is available for Windows XP/Vista/7/8. Click the following link to download the install package and follow the steps in the README-file.

Download MarVis-Suite install package for Windows XP/Vista/7/8 (397 MB)

The MarVis-Pathway database bundle for pathway reconstruction can be found here. When running MarVis-Pathway for the first time, the directory into which these files have been extracted has to be specified.

Example data sets of a multi-omics case study in the context of plant wounding (one transcriptomics DNA microarray and four metabolomics MS data sets) can be downloaded here.

Additionally, a protocol of the data analysis and project files (see Load project function in the File menu of the corresponding MarVis-Suite interface) are available.

MarVis-Suite 1.0: MarVis-Filter and MarVis-Cluster (2011) [1]


The MarVis-Suite 1.0 is available for Windows XP/Vista/7/8. Click the following link to download the install package and follow the steps in the README-file.

Download MarVis-Suite install package for Windows XP/Vista/7/8 (240 MB)

The MarVis-Suite 1.0 documentation can be found here.

Data sets (2011) [1,2]


Download LC/MS raw data matrices (including method description) of the case study for wounding in plants as CSV files (MarkerLynx Marker Report, unpolar extraction phase, negative and positive ionization mode).

The original MarVis(-Cluster) tool (2009) [3]


The original MarVis tool is available for Windows XP/Vista/7/8 and Linux x86. Click the following links to download the install packages and follow the steps in the README-file. MarVis was originally developed for the Windows operating system and then ported to Linux. Therefore we recommend the Windows version. When installing and testing MarVis on Linux (Ubuntu 8.10, Fedora 10, openSuse 11.0) a number of additional packages had to be installed and minor bugs regarding the GUI-elements occurred. For experienced users we have added the corresponding references to the README-file.
