About[edit]
- Alphafold is a Highly accurate protein structure prediction program
- More information at https://github.com/deepmind/alphafold/
How to Run[edit]
- Load alphafold module. This loads alphafold, singularity, and the alphafold databases.
module load alphafold/2.1.1
- Run run_singularity.py to run alphafold. This is a wrapper script for the alphafold singularity container to make things easier to run.
run_singularity.py --data-dir $BIODB --cpus $SLURM_NTASKS --gpus
- The --data-dir parameter should be set to $BIODB. $BIODB points to the location of the alphafold databases
- The --cpus parameter should be set to $SLURM_NTASKS. $SLURM_NTASKS is a variable which is equal to the number of processors you reserved
- The --gpus enables the use of GPUS. Singularity will automatically use the number of the GPUs you have reserved.

Parameters[edit]
- These are all the parameters for run_singularity.py. This can be accessed by running run_singularity.py --help
--fasta-paths FASTA_PATHS [FASTA_PATHS ...], -f FASTA_PATHS [FASTA_PATHS ...] Paths to FASTA files, each containing one sequence. All FASTA paths must have a unique basename as the basename is used to name the output directories for each prediction. --is-prokaryote-list IS_PROKARYOTE_LIST [IS_PROKARYOTE_LIST ...] Optional for multimer system, not used by the single chain system. This list should contain a boolean for each fasta specifying true where the target complex is from a prokaryote, and false where it is not, or where the origin is unknown. These values determine the pairing method for the MSA. --max-template-date MAX_TEMPLATE_DATE, -t MAX_TEMPLATE_DATE Maximum template release date to consider (ISO-8601 format - i.e. YYYY-MM-DD). Important if folding historical test sets. --db-preset {reduced_dbs,full_dbs} Choose preset model configuration - no ensembling with uniref90 + bfd + uniclust30 (full_dbs), or 8 model ensemblings with uniref90 + bfd + uniclust30 (casp14). --model-preset {monomer,monomer_casp14,monomer_ptm,multimer} Choose preset model configuration - the monomer model, the monomer model with extra ensembling, monomer model with pTM head, or multimer model --benchmark, -b Run multiple JAX model evaluations to obtain a timing that excludes the compilation time, which should be more indicative of the time required for inferencing many proteins. --use-precomputed-msas Whether to read MSAs that have been written to disk. WARNING: This will not check if the sequence, database or configuration have changed. --data-dir DATA_DIR, -d DATA_DIR Path to directory with supporting data: AlphaFold parameters and genetic and template databases. Set to the target of download_all_databases.sh. --docker-image DOCKER_IMAGE Alphafold docker image. --output-dir OUTPUT_DIR, -o OUTPUT_DIR Output directory for results. --use-gpu Enable NVIDIA runtime to run with GPUs. --gpu-devices GPU_DEVICES Comma separated list of devices to pass to NVIDIA_VISIBLE_DEVICES. --cpus CPUS, -c CPUS Number of CPUs to use.
