DB2 files generated for DOCK 3.8 will work in 3.7 via SUBDOCK, however they are known to produce spurious error messages. These can be ignored, for the most part, but may add some unwanted noise to your OUTDOCK file.
If you are using 3.7 still, it is possible to prepare a version that keeps everything the same, except without the dangerous "tempconf" message.

Latest revision as of 02:59, 28 December 2023

Important note- although DOCK 3.8 is in the header of this article, SUBDOCK is perfectly capable of running DOCK 3.7 workloads, though some features of DOCK 3.8 will not be taken advantage of.

Installing

git clone https://github.com/docking-org/SUBDOCK.git

IMPORTANT: subdock.bash expects to live in the same directory as rundock.bash!!!

subdock.bash is located @ subdock.bash relative to the repository root.

subdock.bash can be called directly from any location- it is not sensitive to the current working directory.

What's New?

Compared to older scripts, SUBDOCK is easier to use, has more features, and is much more flexible!

December 2022

  • All jobs platforms (e.g slurm, sge) are supported on the same script
  • Subdock can now be run on both db2.gz individual files & db2.tgz packages. A batch_size can be set for both types, allowing for more flexibility.
  • Arguments can be provided environmentally, e.g "export KEY=VALUE" or on the command line e.g "--key=value"
  • Subdock now prints out a superscript to copy-paste on success, convenient for re-submission.
  • Fully restartable on all jobs platforms! See below section for an explanation on what this means, why it matters, and instructions on usage.
  • INDOCK version header is automatically corrected, as are any file paths referenced by INDOCK.

May 2023

  • You can provide http(s) URLs to dockable files as your input in lieu of file paths!
  • Subdock will automatically detect if your jobs failed- no need to use an extra script to check if your jobs have actually finished or not

May 2023

  • A DOCK3R image is now used instead of a DOCK executable, in order to avoid pathological misbehavior witnessed on different systems.

Supported Platforms

There are four platforms currently supported:

  1. SLURM
  2. SGE (Sun Grid Engine)
    • note for BKS lab: the SGE queue on gimel does not have python3, your jobs will not work!
  3. GNU Parallel (for local runs- ideal for testing)
  4. Charity Engine

One of these platforms must be specified- SLURM is the default. These platforms can be set by the

--use-slurm=true
--use-sge=true
--use-parallel=true
--use-charity=true

Arguments, respectively

Using Charity Engine

To use charity engine, you must have access to an executable of the charity engine CLI, as well as GNU parallel.

Additionally, you must provide your charity authentication details in the form of the CHARITY_AUTHKEY or --charity-authkey variable.

WIP, more specific instructions to come.

Supported File Types

DOCK can be run on individual db2.gz files or db2.tgz tar packages.

The file type can be specified via the --use-db2=true or --use-db2-tgz=true arguments. db2.tgz is the default

Each job dispatched by SUBDOCK will consume BATCH_SIZE files, where BATCH_SIZE is equal to --use-db2-batch-size or --use-db2-tgz-batch-size depending on which file type is chosen.

The number of jobs dispatched by SUBDOCK is equal to ceil(N / BATCH_SIZE), where N is the total number of input files.

Restartability

ONLY APPLICABLE FOR DOCK 3.8+!

Restartability means that we can impose arbitrary time limits on how long our jobs can run *without* losing our progress. Time limits can be as large or as small as we want them to be, even as little as a few minutes per job! This flexibility lets docking jobs efficiently fill in the gaps between longer-running jobs on the same ecosystem, thus they will be preferentially treated by whichever system is in charge of scheduling.

How to use for your Job Platform

On SLURM, runtime can be defined with the "--time" argument, e.g:

subdock.bash --use-slurm=true --use-slurm-args="--time=00:30:00"

This will allow our job to run for 30 minutes before progress is saved & copied out.

On GNU parallel this is accomplished with "--timeout", e.g:

subdock.bash --use-parallel=true --use-parallel-args="--timeout 1800"

On SGE, the same can be achieved using the s_rt and h_rt parameters, e.g:

subdock.bash --use-sge=true --use-sge-args="-l s_rt=00:29:30 -l h_rt=00:30:00"

This tells SGE to warn the job 30 seconds prior to the 30 minute hard limit. GNU and SLURM platforms will provide a hard-coded 30 seconds notice, whereas this notice period must be manually defined for SGE jobs.

How to continue jobs

Run subdock.bash again with the same parameters (particularly EXPORT_DEST, INPUT_SOURCE, USE_DB2, USE_DB2_TGZ, USE_DB2_BATCH_SIZE, and USE_DB2_TGZ_BATCH_SIZE) to restart your jobs! If you saved the superscript SUBDOCK spits out on successful submission, you can simply call that.

You'll know there is no more work to be done if SUBDOCK prints "all N jobs complete!", SUBDOCK will also tell you what proportion of jobs have not yet completed on each submission.

Output files are appended with a suffix indicating how many times the docking task has been resubmitted, e.g OUTDOCK.0 for the first attempt, OUTDOCK.1 for the second, etc.

Be careful not to overlap your submissions- there are no guardrails in place to prevent this from happening if you are not careful.

Full Example - All Steps

This example assumes you have access to a DOCK executable and an installed scheduling system (SGE/SLURM/Parallel), but nothing else.

1. Source subdock code from github

git clone https://github.com/docking-org/SUBDOCK.git

2. Fetch dockfiles from DUDE-Z- we will use DRD4 for this example.

# note- SUBDOCK automatically detects your DOCK version & corrects the INDOCK header accordingly
wget -r --reject="index.html*" -nH --cut-dirs=2 -l1 --no-parent https://dudez.docking.org/DOCKING_GRIDS_AND_POSES/DRD4/dockfiles/

3a. Get db2 database subset sample via ZINC-22. Example provided below:

wget http://files.docking.org/zinc22/zinc-22l/H17/H17P050/a/H17P050-N-laa.db2.tgz
wget http://files.docking.org/zinc22/zinc-22l/H17/H17P050/a/H17P050-N-lab.db2.tgz
wget http://files.docking.org/zinc22/zinc-22l/H17/H17P050/a/H17P050-N-lac.db2.tgz

You can select a db2 database subset via cartblanche22.docking.org- for wget-able files, choose the DOCK37 (*.db2.tgz) format, with URL download type. Multiple download types are supported, for example if you are on Wynton you can download Wynton file paths- removing the need to download the files yourself.

3b. If you downloaded the db2.tgz files yourself, create an sdi.in file from your database subset, which will serve as a list of files to evaluate. For example:

find $PWD -type f -name '*.db2.tgz' > sdi.in

4. Export the parameters we just prepared as environment variables. You need a DOCK executable! This can be found via our download server if you have a license, otherwise lab members can directly pull https://github.com/docking-org/dock3.git. On BKS cluster, some curated executables have been prepared with labels @ /nfs/soft/dock/versions/dock38/executables. DOCK 3.7 executables may be found here as well!

export INPUT_SOURCE=$PWD/sdi.in
export EXPORT_DEST=$PWD/output
export DOCKFILES=$PWD/dockfiles
export DOCKEXEC=/nfs/soft/dock/versions/dock38/executables/dock38_nogist

5. Choose a platform. You must select only one platform - mixing and matching is not supported.

export USE_SLURM=true|...
export USE_SGE=true|...
export USE_PARALLEL=true|...

Any value other than exactly "true" will be interpreted as false.

6a. Run docking!

bash ~/SUBDOCK/subdock.bash

6b. You can also use command line arguments instead of environment export, if desired. These can be mixed and matched.

export DOCKEXEC=$PWD/DOCK/ucsfdock/docking/DOCK/dock64
bash ~/SUBDOCK/subdock.bash --input-source=$PWD/sdi.in --export-dest=$PWD/output --dockfiles=$PWD/dockfiles --use-slurm=true

7. After executing subdock, it will print out a convenient "superscript" to copy & paste, for any future re-submissions.

Mixing DOCK 3.7 and DOCK 3.8 - known problems

Headline: Though SUBDOCK is compatible with DOCK 3.7, and will allow docking of ligands built for 3.8 in 3.7, it is NOT RECOMMENDED to do this without using a specially prepared 3.7 executable!

If you're running DOCK 3.8 against recently built ligands, you may encounter error messages that look like this:

       1      2 bonds with error
Error. newlist is not big enough

Or worse, like this:

 Warning. tempconf = 0
         1597 ->            0 ->            0

The latter error messages have the potential to cause some serious damage, as they are emitted very frequently & may consume excessive disk space. SUBDOCK will check for these messages periodically during DOCK's runtime & kill the process if they are found.

If you are on 3.8 and are encountering these messages still, use the dock38_nogist executable described in How_to_install_DOCK_3.8#Prebuilt_Executable. This version voids the code related to the GIST scoring function, which is responsible for these errors.

If you are using 3.7 still, it is possible to prepare a version that keeps everything the same, except without the dangerous "tempconf" message.
