Parameters

  --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.
