Getting started with DOCK 3.7

Jump to: navigation, search

Here are steps to get started with DOCK 3.7 . If you don't already have the necessary physical infrastructure, you'll need to set it up. If you haven't already installed DOCK 3.7, here are the installation instructions.

So, now that you have DOCK 3.7 running, and that basic ./all-test.sh script works, here is how to get started:

Docking preparation from receptor and ligand alone

Here we prepare the endogenous human metabolites for docking.

mkdir -p ~/docking/test1
cd $DOCKBASE/test/data/xiap/proteins/initial
cp rec.pdb xtal-lig.pdb ~/docking/test1/
cd ~/docking/test1/
blastermaster -v

Prepare library for docking

Here we prepare the endogenous human metabolites.

mkdir -p ~/database/testa
cd ~/database/testa
wget http://zinc.docking.org/db/byvendor/hmdbendo/hmdbendo_p0.smi.gz
gunzip hmdbendo_p0.smi.gz
head hmdbendo_p0.smi > top10.smi
build_smiles_ligand top10.smi

If this succeeds without trouble, try a bigger database:

build_smiles_ligand hmdbendo_p0.smi

Dock custom library

Go to the directory where you can see working and dockfiles directories from Test 2 above.

setup_db2_lots 1 jobname ~/database/testd # nb directory from Test 3 above.
submit_dock

If you want to submit each db2.gz as a separate job, just use

setup_db2 <db_dir>

where <db_dir> is the directory containing the .db2.gz database files.

Run DUD and DUDE benchmarks =

      • NB THIS SECTION IS STILL IN DEVELOPMENT ***

And generate statistics to assess how well docking is working.

Acquire public library and dock it

Use ZINC Subset DB2 file locations to locate mol2db2 format libraries of popular subsets until they are available in ZINC (later in 2014).

Dock starting from PDB code

  • Run be_blasti
  • run blastermaster (see Test 2 above)
  • run docking (see test 4 above)

Perform fine-tuned docking run

fine tune docking spheres (hot spots)

  • step 1
  • step 2
  • step 3

fine tune VDW spheres

  • step 1
  • step 2
  • step 3

fine tune bounding box

  • step 1
  • step 2
  • step 3

handle ZINC ion and its coordinating residues

  • step 1
  • step 2
  • step 3

fine tune electostatics (tarting up)

  • step 1
  • step 2
  • step 3

fine tune other features of docking (enumerate)

  • one
  • two
  • three
