Alanine Scanning module

Submodules

haddock.modules.analysis.alascan.scan module

Module contents

HADDOCK3 module for alanine scan.

This module is responsible for the alanine scan analysis of the models generated in the previous step of the workflow. For each model, the module will mutate the interface residues and calculate the energy differences between the wild type and the mutant, thus providing a measure of the impact of such mutation.

If cluster information is available, the module will also calculate the average energy difference for each cluster of models.
