Break ties

When your dataset has multiple points with the exact same value, it can cause problems with data transformation. Breaking ties, sometimes called despiking, is a way to avoid that. When you break ties, you add tiny random numbers to all the data values. This task adds a unique random number between 10^-7 and 10^-6 to each data value.

Parameters

• source (geoscience object reference)
  • A geoscience object reference that points to a one-dimensional continuous attribute inside a pointset or downhole-intervals object.
• target (geoscience object reference)
  • A geoscience object reference that tells the task where to save the result. It must point to an attribute inside a pointset or downhole-intervals object.
• random_seed (integer, optional)
  • Seeds random number generation in the task. Defaults to 123456789.

Tips

• The source and target can use the same object, but they don't have to.
