Chain background and Demo

Chain: A subset a, with: b

  1. Based on the Hasse diagram a start vertex "start" and a sink vertex "sink" is to be selected.

  2. Note: start < sink, i.e. the chain module is searching for paths upwards.

  3. Furthermore a selection is to be done, how many vertices should be in a chain:

    The corresponding variable is called maxch.

  4. If “start” and "sink" and "maxch" are appropriately selected chains are identified.

    The result is a matrix where chain i is compared with chain j and its similarity due to the Tanimoto-Index is calculated:

c

  1. The matrix T is also displayed as bar diagram.
  2. Chains which are of interest can be selected and objects belonging to the selected chain are displayed.
