This tutorial uses the DOCK-3.7-beta3. This is a supplemental tutorial for DOCK 3.7 2015/04/15 abl1 Tutorial. Former one works well and is very simple and clear. This tutorial mentions some updates in job submissions.

This is for a Linux environment and the scripts assume that you are running on SGE queueing system.

Submit an enrichment calculation via new 0003.lig-decoy_enrichment.csh

In this section we present a modified version of script here [[1]].

Here we modify the script to use an array job rather than submit every chuck individually as was done previously.

  • Go to the working directory of your account
cd /nfs/home/$USERNAME/work/DOCK_tutorial

PS: $USERNAME is your username log on the cluster.

The hierarchy of the working directory:

DOCK_tutorial ----- 2HYY ------ dockfiles
              |          |
              |          |----- working
              |          |
              |          ------ other files generated by 0001.be_balsti_py.csh
              |
              ----- databases ------ decoys
                              |
                              |----- ligands
                              |
                              ------ ligands.ism and decoys.ism files

The 0003_new.lig-decoy_enrichment.csh script above will ONLY submit one job but with 1-many subjobs.

Submit an enrichment calculation via 0003.lig-decoy_enrichment_submit.csh

We recommend using this method, rather than the earlier scripts, as it uses the DOCK submission infrastructure.
