AlphaFold
Description
This package provides an implementation of the inference pipeline of AlphaFold v2.3. This is a completely new model that was entered in CASP14 and published in Nature. For simplicity, we refer to this model as AlphaFold throughout the rest of this document.
Environment Modules
Run module spider alphafold to find out what environment modules are available for this application.
Additional Information
Note that Alphafold has large memory requirements and some of its stages use 4 or 8 CPUs in addition to a GPU. An example job script for a run with the test data included with the software is shown below.

Usage Example
To simplify the usage use the 'alphafold_full_db.sh' script. Simple run example:
alphafold_full_db.sh --fasta_paths=${HPC_ALPHAFOLD_REF}/test.fasta --output_dir=~/scratch --max_template_date=2020-05-14 --use_gpu_relax=1
From version 2.3, the AlphaFold documentation recommends running as Docker container. However, Docker is not compatible with the HPC. AlphaFold has been installed as an apptainer container and the alphafold_full_db.sh wrapper script has been created to mimic the behavior of docker/run_docker.py as referenced in the AlphaFold documentation. alphafold_full_db,sh will specify the database location options required by alphafold.
To specify these options manually, use run_alphafold.sh instead.
If using the --model_preset=multimer option, use the alphafold_multimer_db.sh launch script instead. Example:
alphafold_multimer_db.sh --model_preset=multimer --fasta_paths=${HPC_ALPHAFOLD_REF}/test.fasta --output_dir=~/scratch --max_template_date=2020-05-14 --use_gpu_relax=1
