Gene expression or metabolomics data generated from clinical studies are often associated with multiple clinical parameters or metadata (i.e. diagnosis, genotype, survival, gender, etc.). It is of great interest to analyze as well as to visualize the data with regard to these metadata. To address this issue, we have developed INVEX - an easy-to-use, highly interactive web-based tool that allows researchers to perform flexible differential expression analysis with regard to different metadata and to visually explore the results within the context of metadata and biological annotations. In addition, INVEX allows users to easily create custom heatmaps from interesting expression patterns and enriched functional categories. INVEX main features:

  • Data annotation for common gene and metabolite IDs;
  • Built-in support for a wide variety of common as well as complex analyses of differential expression;
  • Enrichment analysis to highlight meaningful biological pathways or functional groups;
  • Visual data exploration and pattern discovery by interactive heatmaps;
  • An intuitive heatmap builder for creating custom heatmaps.
