geneXplain platform

Platform release 4.13 is available now
The comprehensive bioinformatics platform, with geneXplain‘s proprietary Upstream Analysis as particular feature
The geneXplain platform is an online toolbox and workflow management system for a broad range of bioinformatic and systems biology applications. The individual modules, or Bricks, are unified under a standardized interface, with a consistent look-and-feel and can flexibly be put together to comprehensive workflows. The workflow management is intuitively handled through a simple drag-and-drop system.
With this system, you can edit the predefined workflows or compose your own workflows from scratch.
Own Bricks can easily be added as scripts or plug-ins and can be used in combination with pre-existing analyses.

GeneXplain GmbH provides a number of state-of-the-art bricks; some of them can be obtained free of charge, while others require licensing for small fee in order to guarantee active maintenance and dynamic adaptation to the rapidly developing know-how in this field.

Key features

Integrated databases and analysis tools

The platform provides an integrated view on several databases and analysis tools, public domain as well as commercial ones. They can be combined in a highly flexible way to design customized analyses.

Ready-made workflows for an easy start

A rapidly growing number of proven workflows facilitates a quick and easy access to the platform and its complex analysis functions. Input forms are simple and user-friendly. Workflows can be easily customized to specific needs. Experienced users can create their own workflows.

Fully integrated upstream analysis

The platform provides a fully integrated upstream analysis, which combines state-of-the-art analysis of regulatory genome regions with sophisticated pathway analyses.

Knowledge-based data analysis

The platform uses a number of renowned high-quality databases for the data analysis. TRANSFAC® and TRANSPATH® are expert-curated databases. GeneWays is generated by an NLP-based text-mining approach, providing a helpful complement for manually curated data. Well-known public-domain databases like Reactome and HumanCyc are integrated and applied as well.

JavaScript and R scripts

User-specific scripts in JavaScript and in R can be added directly into the platform, and immediately executed. They can be combined with pre-existing analyses, and can be part of the workflows.

NGS data analysis

NGS data analysis is supported by the platform. ChIP-seq data sets containing in vivo transcription factor binding sites or methylation results can be analyzed with the help of ready-made workflows. Galaxy tools are integrated, supporting RNA-seq data analysis, and many functions more.

Simulation engine inside

The platform contains a simulation engine that executes differential equation systems and visualizes the results. Parameter optimization, parameter fitting (based on expression data), and hierarchical modeling are supported.

Group project work including chat function

Share your data and results with other members of the project. Discuss what you are doing while working together on a dataset.

  • Update to Ensembl 91 database
  • Update to Reactome 63 database

RELEASE 4.8

  • New analysis methods

Construct composite modules on track (correlation) – method predicts composite module using the result of the “Site search on gene set” analysis.

Cluster track – method clusters sites in a track, what is useful for merging of closely spaced sites into one big cluster.

Compute profile thresholds – method computes profile thresholds minimizing either false negatives(minFN) or false positive(minFP) on the random DNA sequence.

Create miRNA promoters – method extracts miRNA promoters from mirprom database for a given list of miRNAs

Get transcripts track – method extracts track from a database by a transcript ID

Recalculate composite module score on new track – method takes best composite model from the given CMA result and calculates its scores on all sites of a given track.

Continue CMA – method continues prediction of composite module using results of the previous prediction as a start point. Prediction parameters are customizable.

Table Imputation – method replaces missing data in the given input table with row means.

  • New HTML report for site search analysis

You can now create a summary of your site search analysis including visualization of input promoters together with identified enriched transcription factor binding sites (TFBSs) in HTML format, which can be exported to your local computer.

Demo Workflows

Here, we list workflows that were used to prove the capabilities of the geneXplain platform, for instance in the cited publications. The links given direct you straight into the platform without requiring any registration.
Using these demo workflows, you will be able to reproduce the published results and to learn more about the platform’s look and feel. To work with your own data, however, registration is required. Additional licensing is necessary for certain third-party products such as TRANSFAC® or TRANSPATH®.
Workflows 1-3 are from our recent publication Koschmann et al., Microarrays 4, 270-286.

Workflow management

Sequential launching of particular analysis modules can be saved as a graphically represented workflow. Modules are shown as purple rectangles, and outputs of each step serve as inputs into the next analysis step. A workflow that is specific for a given data set can be easily constructed by drag and drop of the required analysis modules. In addition, Java scripts and R scripts can be added directly within the platform, for more specific requirements of the analysis.
The picture shows a small workflow for the gene set enrichment analysis (GSEA) of using four different ontologies: Gene Ontology (GO) Biological Process, GO Cellular Compartment, GO Molecular Function, and Reactome's functional assignments (see on the right side). The larger light blue boxes are analysis functions (program modules, "Bricks"). Green boxes stand for input files, especially user-defined inputs. Yellow boxes represent automatic delivery or output files. A workflow can be intuitively designs by simple drag-and-drop of the constituents and graphically connecting them.
