Provides:

  • Visualisation of all the features in your dataset
  • Ability to explore the correlations driven from any feature of choice
  • Suggestion of structural sets (i.e., features putatively resulting from the same compound)
  • Ability to change the correlation method, threshold, FDR correction method
  • Ability to change the correlation threshold and retention time window for defining structural sets

Exports:

  • Basic tabular csv of all results (feature names, correlations, structural sets, etc.)
  • Interactive html plots (plotly)
