HADDOCK2.2 manual

Installation

HADDOCK consists of a collection of python and CNS scripts and other additional scripts and programs (csh, awk or gawk, perl, c++). We have been running HADDOCK without problems on linux and MacOSX systems. HADDOCK has also been installed on IBM and SGI systems, requiring modifications in some scripts to properly define the path of awk or gawk. Installation on other architectures should work but has not been tested.

Important: Python version 2.7 or higher (not tested on 3>) and CNS needs to be recompiled with the files provided in the haddock2.2/cns1.3 directory in order to use the new HADDOCK2.2 features (like radius of gyration and pseudo-contact shifts restraints.

Note that HADDOCK is NOT supported on Windows systems.

The HADDOCK distribution comes as a gzipped tar file haddock2.2.tgz. To install HADDOCK uncompress this file and untar it with: 
    tar xvfz haddock2.2.tgz
This will create a directory called haddock2.2 containing various subdirectories:
  • Haddock: contains all the python scripts

  • cgi: cgi scripts (these are installed on our web server). You can install them locally on your server and modify the html files to access them.

  • cns1.1: contains a number of CNS routines (including the VEAN statement) with a few small modifications use with HADDOCK. We recommend to recompile CNS with these routines.

  • cns1.2: contains a number of CNS routines (including the VEAN statement) with a few small modifications use with HADDOCK. We recommend to recompile CNS with these routines.

  • doc: contains a README file pointing to the online HADDOCK manual

  • examples: contains examples for running HADDOCK

  • examples-run-data: contains a script with which pre-calculates example runs can be downlaoded

  • protocols: contains the CNS scripts

  • tests: a short version of the examples to test modifications to the sofware

  • tools: contains various awk, csh and perl scripts for preparation of PDB files and analysis

      NOTE: check that the correct location of awk, gawk and perl are defined for your system in the various awk and perl scripts.

  • toppar: contains CNS topology and parameter files.

  • RDCtools: contains scripts (python and gawk) to generate RDC restraints (SANI) or intervector projection angle restraints (VEAN) including examples. See RDC restraints for information.

  • DANItools: contains scripts (csh and gawk) to generate diffusion anisotropy restraints (DANI) , calculate tensor parameters and analyze PDB files. See DANI restraints for information.


In the main haddock directory you will find setup files named haddock_configure.csh and haddock_configure.sh which you should edit to define a number of environment variables. Two examples are provided (for setup under MacOSX and linux) 
#!/bin/tcsh
#
# HADDOCK configuration file
#
#
setenv HADDOCK /home/abonvin/haddock2.2
setenv HADDOCKTOOLS $HADDOCK/tools
setenv PYTHONPATH $HADDOCK
alias  haddock2.2 `which python` $HADDOCK/Haddock/RunHaddock.py
#
# Define location of third party software
#
setenv NACCESS /software/bin/naccess
setenv PALES   /software/bin/pales
setenv PROFIT  /software/bin/profit
setenv TENSOR2 /software/bin/tensor2
    Note that this is a csh/tcsh script. An example of a bash script is also provided.

Also control the various scripts in the tools directory for a proper definition of the location of gawk (or awk if gawk is not installed) and perl and compile the various C++ programs in the tools directory by typing in the main haddock directory: 
   make clean; make
If needed, edit the Makefile files in tools to define the c++ compiler and compiler flags.

To initialize and run HADDOCK then simply source the haddock_configure.csh file with e.g. under csh/tcsh: 
   source haddock_configure.csh
Before running HADDOCK2.2 you need of course to install python version 2.7 or higher and CNS.

The additional required software and licenses required to run HADDOCK (e.g. CNS) should be obtained directly from the distribution sites. (see the software links).

Special topics:

If you are going to run HADDOCK without using a queuing system, e.g. simply csh, it is recommended to use full pathnames for the job files. This can be defined in the python file UseLongFilename.py located in the Haddock/Main directory.

In our environment, we are making use of various queuing systems (PBS, torque) with wrapper scripts that require the jobs to be submitted from the local directory. Because of that our default setup does not use long filenames, i.e. useLongJobFileNames is set to 0.
