How to dock in DOCK3.8

How to dock in DOCK 3.8.0

Differences from DOCK.3.7

DOCK 3.8.0 can be interrupted safely and restarted, which allows more flexibility when submitting docking jobs.

For example, you could set QSUB_ARGS="-l s_rt=00:05:00 -l h_rt=00:07:00" (or SBATCH_ARGS="--time=00:07:00") so that each docking job will only run for 5 minutes before being interrupted. The new subdock.bash script allows submitting the same set of jobs multiple times, until they are all complete.

Running the Script

New subdock scripts are here:

$DOCKBASE/docking/submit/sge/subdock.bash $DOCKBASE/docking/submit/slurm/subdock.bash

subdock.bash requires a number of environmental variables to be passed as arguments.

Required Arguments

INPUT_SOURCE

INPUT_SOURCE should be either:

a) A directory containing one or more db2.tgz files OR

b) A text file containing a list of paths to db2.tgz files

EXPORT_DEST

A directory on the NFS where you would like your docking output to end up. If the directory does not exist, the script will try to create it.

DOCKEXEC

An NFS path to a DOCK binary executable (NOT a wrapper script).

DOCKFILES

An NFS path to the dockfiles (INDOCK, spheres, receptor files, grids, etc.) being used for this docking run. The dockfiles directory should be named uniquely, to avoid confusion with other dockfiles other users may be running.

Optional Arguments

SHRTCACHE

The directory DOCK will perform it's work in. Files saved to this directory will be deleted once the docking job has concluded. By default this is /dev/shm.

LONGCACHE

The directory DOCK will store files that are shared between multiple docking jobs. Files saved to this directory (dockexec and dockfiles) will persist until they are deleted. By default this directory is /tmp.

Beware of using the default SHRTCACHE or LONGCACHE settings on large clusters.

SBATCH_ARGS

Additional arguments to provide to slurm's sbatch, if using the slurm version of subdock.bash.

QSUB_ARGS

Additional arguments to provide to sge's qsub, if using the sge version of subdock.bash

Example: Running a lot of docking jobs

• 1. set up sdi files

mkdir sdi
export sdi=sdi
ls /wynton/group/bks/zinc-22/H19/H19P0??/*.db2.tgz > $sdi/h19p0.in
ls /wynton/group/bks/zinc-22/H19/H19P1??/*.db2.tgz > $sdi/h19p1.in
ls /wynton/group/bks/zinc-22/H19/H19P2??/*.db2.tgz > $sdi/h19p2.in
ls /wynton/group/bks/zinc-22/H19/H19P3??/*.db2.tgz > $sdi/h19p3.in
and so on

• 2. set up INDOCK and dockfiles. rename dockfiles to dockfiles.$indockhash. On some nodes, the shasum command is called by sha1sum. Ultimately, renaming the dockfiles to a unique dockfiles is key.

bash
indockhash=$(cat INDOCK | shasum | awk '{print substr($1, 1, 12)}')

• 3. super script:

export DOCKBASE=/wynton/group/bks/work/jji/DOCK
export DOCKFILES=$WORKDIR/dockfiles.21751f1bb16b
export DOCKEXEC=$DOCKBASE/docking/DOCK/bin/dock64
#export SHRTCACHE=/dev/shm # default
export SHRTCACHE=/scratch
#export LONGCACHE=/scratch # default
export QSUB_ARGS="-l s_rt=00:28:00 -l h_rt=00:30:00 -l mem_free=2G"

for i in  sdi/*.in  ; do
        export k=$(basename $i .in)
	echo k $k
	export INPUT_SOURCE=$PWD/$i
	export EXPORT_DEST=$PWD/output/$k
	$DOCKBASE/docking/submit/sge/subdock.bash
done
