NodeEnrichment Plotter (deprecated)


This node draws enrichment curves often used in virtual screening. For this the user can choose a column by which the data is sorted and represents the x-axis. The values on the y-axis are formed by the sum of the hits in a second column that is also selected by the user. A row is considered a hit if the value is greater than 0. The steeper the resulting curve, the better the enrichment is. Optionally the y-axis can show the sum of the hit values instead of the number of hits.
The two gray lines in the view show the enrichment if the data points were ordered randomly (lower diagonal) and the optimal enrichment if all hits are ordered before the first non-hit (upper diagonal).

Input ports

  1. Input table Type: Data
    Input data with predicted values and actual values

Output ports

  1. Areas under curve Type: Data
    A one-column table with the area(s) under the enrichment curve(s)
  2. Discovery rates Type: Data
    Table with the discovery rates (either hits or clusters) for the different curves at selected points (given as fraction of the complete dataset).
