The 3D pipeline is a collection of scripts and software packages that enable the massively parallel creation of dockable 3D molecules.
- Chemaxon License (email John for license details)
- Openeye License (email John for license details)
- Corina License (comes packaged with the executable, so you will need to provide the executable)
- SGE or SLURM queueing system installed on your cluster
- A networked file system installed on your cluster
- clone the appropriate branch of the zinc-3d-build-3 repository (github link) to your working directory
- Secure copy the software distribution from our cluster at (scp link)
- Extract the software distribution to the $HOME/soft directory of the user that will be running the script
- When this script is submitted to a machine for the first time, it will copy and install the necessary software from $HOME/soft to local storage
- Because of this, it is important that your $HOME be global if you are running the script unmodified
- If you don't have a global home, or otherwise want your software to reside somewhere else, you can specify an alternative global directory to copy the software from by exporting SOFT_HOME prior to running submit-all-jobs.bash (see below)
- Copy your licenses into the same directory you extracted the software to. Copy your corina distribution (as a tar.gz) into this same folder.
- This script assumes that the jchem and openeye licenses will be named ".jchem-license.cxl" and ".oe-license.txt" respectively. Corina is assumed to be named "corina.tar.gz"
Running The Script
export INPUT_FILE=$YOUR_INPUT_FILE.smi export OUTPUT_DEST=$SOME_GLOBAL_DIRECTORY # if you don't have a global home directory (but some other global directory available), specify an alternate SOFT_HOME # export SOFT_HOME=$YOUR_SOFT_HOME export LINES_PER_BATCH=50000 export LINES_PER_JOB=50 ./submit-all-jobs-<slurm/sge>.bash
export INPUT_FILE=example.smi export OUTPUT_DEST=/nfs/exb/zinc22/tarballs export SBATCH_ARGS="--time=00:45:00 --requeue" export LINES_PER_BATCH=50000 export LINES_PER_JOB=50 export TEMPDIR=/dev/shm ./submit-all-jobs-slurm.bash
export INPUT_FILE=example.smi export OUTPUT_DEST=/wynton/group/bks/zinc22 export QSUB_ARGS="-l s_rt=00:28:30 -l h_rt=00:30:00 -r y" export LINES_PER_BATCH=50000 export LINES_PER_JOB=50 export TEMPDIR=/scratch ./submit-all-jobs-sge.bash
export INPUT_FILE=example.smi export OUTPUT_DEST=$SCRATCH/zinc22 export SBATCH_ARGS="--time-min=01:00:00 --time=02:00:00 --requeue -q flex -C haswell" export LINES_PER_BATCH=50000 export LINES_PER_JOB=50 export TEMPDIR=$SCRATCH ./submit-all-jobs-slurm.bash
Input And Output
The input .smi file to be built. This file should contain only two columns of data: (SMILES, NAME) with no header.
The base directory for output to be stored. The script will create a sub-directory here named $INPUT_FILE.batch-3d.d
Within this output directory there are 3 sub-directories:
In contains the input file split into fragments and sub-fragments. By default the script first splits the input file into batches of 50000, then splits those batches into sub-batches of 50. Each individual job works on one of these sub-batches. Each array batch job works on one of the batches of 50000. All of the other directories alongside 'in' share the same directory structure.
Log contains log messages from the jobs. If you are re-submitting a file, be aware that log messages from previous runs on this file will be overwritten.
Out contains tar.gz output from each job. The tarballs should contain a number of 3d molecule formats for each molecule in the batch, including 1 or more db2.gz files.
How many lines of the source .smi file should be processed per array batch job
How many lines of the batch .smi file should be processed per array task
Sometimes an output tarball will have few or no entries within. Certain molecule types [elaborate] will fail to be built, and often these molecules get bunched together (i.e if the input file is sorted by SMILES). Additionally, a small percentage of all molecules may fail to be processed by corina or amsol. If neither of these explain what is causing your missing entries, check that tarball's corresponding log entry for more info. Mail me @ firstname.lastname@example.org for additional technical support.
This script was designed for a 64 bit architecture. You will likely run into some library issues trying to run it on 32 bit machines. If that's all you have you can try to swap out libg2c.so.0* in lib.tar.gz with a 32 bit version, but I cannot help you beyond that.
It is safe to re-run the same file multiple times- the script takes care of making sure not to re-run any jobs that have already completed successfully prior. This is only the case if that file's corresponding batch-3d.d output directory has not been moved or deleted.
For example, if one of your nodes went down and caused a bunch of jobs to fail, it would be safe to re-run ./submit-all-jobs.bash to re-submit those jobs. (assuming there are no jobs for that file currently queued/running)
