General Description

Our Global Clustering tool aims to help users vizualize Champions PDX models in a T-SNE and overlay gene expression or agent response data. Your in-house RNASeq data can be uploaded and aligned in a T-SNE or overlaid in a UMAP with TCGA or Champions PDX model data.

Global Clustering Inputs

  1. Analysis. Choose between Champions t-SNE, TCGA t-SNE or PDX TCGA + UMAP.
  2. Dataset. Choose from the dropdown menu between Champions PDX, Champions Cell Lines Data or TCGA.
  3. Cancer Type. Select cancer type of interest from the dropdown menu or leave blank for all cancer types. Please Note: A specific cancer type is required for all datasets other than Champions PDX.
  4. Gene Expression. Select your genes of interest. Only options with available data for your other selections will be clickable. Options that are greyed out have no available data for your other selections.
  5. Agent Activity. Select specific test agents with available data or leave blank for all available test agents with data.
  6. Bookmark. Save an analysis or load from an existing analysis. Please Note: As we are continually updating our data the visualization may change slightly from the time it was first analyzed. Users can also manage all bookmarks under "My Bookmarks" in Account Settings at the top right of any Lumin page.
  7. View.
  8. CSV. After clicking 'View' you can also download the results as a CSV file by clicking this button.
  9. Loading Task Bar. Building your requested visualization may take some time. The status of your request will be displayed here.

Global Clustering Visualization

This plot shows the similarity between the Champions PDX samples for visual analytics, where the similarity for each point is visualized as proximity of the points. Sample points that are ‘similar’ are placed close to each other.

Available Data

Champions PDX
