haddock-tools

Important❗

Please note that most scripts here are out-dated!

While some of them might still work, it is recommended to check our utilities currently in development, such as:

pdb-tools - for all things PDB-related
haddock-runner - for running running large-scale HADDOCK jobs
haddock-restraints - for all things related to generating restraints for HADDOCK

Set of useful HADDOCK utility scripts, which requires Python 3.7+.

About

This is a collection of scripts useful for pre- and post-processing and analysis for HADDOCK runs. Requests for new scripts will be taken into consideration, depending on the effort and general usability of the script.

Installation

Download the zip archive or clone the repository with git. This last is the recommended option as it is then extremely simple to get updates.

# To download
git clone https://github.com/haddocking/haddock-tools

# To compile the executables
cd haddock-tools
make

# To update
cd haddock-tools && git pull origin master

Scripts

Benchmark-related

AnalyseBenchmarkResults.py

This python3 script works together with the haddock-runner as a post-processing tool to analyse multiple scenarios performances. Note that it is deticated to the analysis of runs performed by haddock3 as it relies on reading the content of the [caprieval] module outputs.

Three major plots will be generated:

capri-barplots: Standard best performing model among top X models, using CAPRI model quality assessment (high, medium, acceptable, near-acceptable and low quality models)
violin-plots: Dispersion of the tracked metric among top X models.
melqui-plots: Analysis of the top ranked 200 models using CAPRI quality assessment. Copyleft Adrien Melquiond.

pip install numpy matplotlib

Requirements:

FreeSASA

pip install freesasa

BioPython

pip install biopython

Usage:
