====== Settings ======
Settings are used to configure the [[pathways|pathway]] prediction, and include a list of package/s and a truncation strategy:

  * Packages: all available [[rules|rules]] within the selected packages are used for pathway prediction.
  * Truncation strategy limits the combinatorial explosion in pathway prediction. A truncation strategy can include:
      -A [[relative_reasoning|relative reasoning model]] and a probability threshold.
      -Basic truncators like e.g. [[rules|RuleLikelihood]], or Maximum Number of Nodes.

Users can use an existing setting or create their own by navigating to the Settings tab while logged in with their username and password.

===== Available Settings =====

**Legacy Eawag-PPS Setting**
This setting generates predicted pathways based on the legacy rules available in the original [[https://eawag-bbd.ethz.ch/predict/aboutPPS.html| Eawag-PPS]]. Using this setting for predictions will apply the biotransformation rules from the Eawag-PPS to the parent molecule, and predict products based on the functional groups present on the parent molecule.

**Global Default Setting**
