text: user274: I am searching for a multi-omics dataset which may include genomics, transcriptomics and proteomics (eg. snyderome).
  I need such a dataset for an introductory data-exploration purpose. So it can be from any host organism and any experimental methods/conditions.
  Is there any database/repository where I can find it?
  
  user476: Next to OmicsDI the EBI has a special repository for multi-omics datasets: https://www.ebi.ac.uk/biosamples
  It links the different datasets between repositories, ie. PRIDE for MS/MS based data and ArrayExpress for RNASeq data.
  
  user563: There are several datasets available on GEO, though you do have to search for them. For example, here are three data sets that have both Illumina methylation and gene expression microarray profiling:
  
  GSE87650
  GSE72874
  GSE56047
  
  
  user274: There is a database called OmicsDI, where one can search for multi-omics datasets.
  Here's a link of the associated publication (Perez-Riverol, Yasset, et al. "Omics Discovery Index-Discovering and Linking Public Omics Datasets." bioRxiv (2016): 049205.) for more details.
