Milestone Module - Heatmap 1.0

For the implementation of the Heatmap representation of glycomics data in GRITS the project is divided in three parts:

• Object model to represent the data in memory
• Clustering algorithm
• Interactive GUI in GRITS

Object model

• List of data sets (columns) with each data set
  • ID
  • Meta data
  • List of Properties with each property
    • ID
    • Numerical value
    • Meta data
• (optional) Meta data related to the clustering

GUI representation in GRITS

• Each cell is represented as colored square
• Data sets ID in the bottom of the data area
• Property ID on the right of the data area
• A legend below to explain color scale based on numerical value
• Coloring can be done linear, ex or ln(x) based
• It is possible to define a lower and upper threshold
• Interaction
  • Export/print graph (e.g. pdf)
  • Mouse over cell shows numerical value

Clustering

• It should be possible to cluster
  • By data set only
  • By property only
  • By data set and property
• Clustering only changes the order of properties and data sets in the data model and provides the information for the dendrogram
