Case studies

• Uploading data to ZENBU
  • Uploading annotation from other sources : UCSC repetitive elements track
• Data processing, visualization and download
  • RNAseq overview
    • using gene model to mask only known exonic expression signal
    • using gene model to collate exonic expression signal for display or download
  • shortRNA overview
    • using mirBase model to collate expression signal for display or download
    • using paraclu to delineate small RNA strucure and expression levels from mapping data
  • CHiP-seq overview
  • Processing CAGE data
    • Clustering CAGE along predefined regions
      In this case study we will illustrate how to vizualize CAGE based expression (yellow background track) along predefined clusters (blue background track) and collate expression onto themc (green background track). The example below uses the FANTOM4 CAGE data and significant clusters boundaries geenrated by the FANTOM4 consortium in The transcriptional network that controls growth arrest and differentiation in a human myeloid leukemia cell line Nat Genet. 2009 May;41(5):553-62.
