Multiomix is an interactive cloud-based platform that allows biologists to identify genetic and epigenetic events associated with the transcriptional modulation of cancer-related genes through the analysis of multi-omics data available on public functional genomic databases. Multiomix consists of an integrated set of functions, pipelines, and a graphical user interface that allows retrieval, aggregation, analysis and visualization of different omics data sources. After the user provides the data to be analyzed, Multiomix identifies all significant correlations between mRNAs and non-mRNA genomics features (e.g.: miRNA, DNA methylation and CNV) across the genome, the predicted sequence based interactions (e.g., miRNA-mRNA), and their associated prognostic values.
