AlphaFold

Description

alphafold website  

This package provides an implementation of the inference pipeline of AlphaFold v2.0. 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.

System Variables

• HPC_ALPHAFOLD_DIR - installation directory
• HPC_ALPHAFOLD_BIN - executable directory

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.

Version 2.1.2

run_alphafold.py \
    --data_dir "${HPC_ALPHAFOLD_REF}" \
    --output_dir $(pwd) \
    --fasta_paths query.fasta \

module load alphafold

'''Version 2.0.0'''
run_alphafold.sh -d $HPC_ALPHAFOLD_REF \
                 -o test/ -m model_1 \
                 -f /apps/alphafold/2.0.0/alphafold/example/query.fasta \
                 -t 2020-05-14
date

Usage Example

To simplify the usage use the 'run_alphafold.sh' script. Simple run example:

run_alphafold.sh -o test/ -m model_1 -f query.fasta -t 2020-05-14

By default run_alphafold.sh will use the 2.2 TB of pre-downloaded reference data in $HPC_ALPHAFOLD_REF.

To access all options use the run_alphafold.py script.
