SUBDOCK DOCK3.8
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?
For those of you that have used a subdock utility before, here's what is new in this release:
1. All jobs platforms (e.g slurm, sge) are supported on the same script
2. GNU Parallel is now supported as a jobs platform! Ideal for small-scale local testing. https://www.gnu.org/software/parallel/
3. 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.
4. Arguments can be provided environmentally, e.g "export KEY=VALUE" or on the command line e.g "--key=value"
5. Subdock now prints out a superscript to copy-paste on success, convenient for re-submission.
6. Fully restartable on all jobs platforms! See below section for an explanation on what this means, why it matters, and instructions on usage.
Supported Platforms
There are three platforms currently supported:
1. SLURM
2. SGE (Sun Grid Engine)
3. GNU Parallel (for local runs- ideal for testing)
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
Arguments, respectively
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
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.
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.
Full Example - All Steps
This example assumes you have access to a DOCK executable, 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.
Error Messages in my OUTDOCK!
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
If these messages bother you 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.
Note on Backwards Compatibility With DOCK 3.7
Previously it was said that SUBDOCK is compatible with DOCK 3.7- this is true, but with a caveat.
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.
