Introduction

nf-core/proteinfold is a bioinformatics best-practice analysis pipeline for Protein 3D structure prediction.

The pipeline is built using Nextflow, a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It uses Docker/Singularity containers making installation trivial and results highly reproducible. The Nextflow DSL2 implementation of this pipeline uses one container per process which makes it much easier to maintain and update software dependencies. Where possible, these processes have been submitted to and installed from nf-core/modules in order to make them available to all nf-core pipelines, and to everyone within the Nextflow community!

On release, automated continuous integration tests run the pipeline on a full-sized dataset on the AWS cloud infrastructure. This ensures that the pipeline runs on AWS, has sensible resource allocation defaults set to run on real-world datasets, and permits the persistent storage of results to benchmark between pipeline releases and other analysis sources. The results obtained from the full-sized test can be viewed on the nf-core website.

Pipeline summary

Alt text

  1. Choice of protein structure prediction method:

    i. AlphaFold2 - Regular AlphaFold2 (MSA computation and model inference in the same process)

    ii. AlphaFold2 split - AlphaFold2 MSA computation and model inference in separate processes

    iii. ColabFold - MMseqs2 API server followed by ColabFold

    iv. ColabFold - MMseqs2 local search followed by ColabFold

    v. ESMFold - Regular ESM

Usage

Note

If you are new to Nextflow and nf-core, please refer to this page on how to set-up Nextflow. Make sure to test your setup with -profile test before running the workflow on actual data.

Now, you can run the pipeline using:

nextflow run nf-core/proteinfold \
   -profile <docker/singularity/.../institute> \
   --input samplesheet.csv \
   --outdir <OUTDIR>

The pipeline takes care of downloading the databases and parameters required by AlphaFold2, Colabfold or ESMFold. In case you have already downloaded the required files, you can skip this step by providing the path to the databases using the corresponding parameter [--alphafold2_db], [--colabfold_db] or [--esmfold_db]. Please refer to the usage documentation to check the directory structure you need to provide for each of the databases.

  • The typical command to run AlphaFold2 mode is shown below:

    nextflow run nf-core/proteinfold \
        --input samplesheet.csv \
        --outdir <OUTDIR> \
        --mode alphafold2 \
        --alphafold2_db <null (default) | DB_PATH> \
        --full_dbs <true/false> \
        --alphafold2_model_preset monomer \
        --use_gpu <true/false> \
        -profile <docker/singularity/podman/shifter/charliecloud/conda/institute>
  • Here is the command to run AlphaFold2 splitting the MSA from the prediction execution:

    nextflow run nf-core/proteinfold \
        --input samplesheet.csv \
        --outdir <OUTDIR> \
        --mode alphafold2 \
        --alphafold2_mode split_msa_prediction \
        --alphafold2_db <null (default) | DB_PATH> \
        --full_dbs <true/false> \
        --alphafold2_model_preset monomer \
        --use_gpu <true/false> \
        -profile <docker/singularity/podman/shifter/charliecloud/conda/institute>
  • Below, the command to run colabfold_local mode:

    nextflow run nf-core/proteinfold \
        --input samplesheet.csv \
        --outdir <OUTDIR> \
        --mode colabfold \
        --colabfold_server local \
        --colabfold_db <null (default) | PATH> \
        --num_recycles_colabfold 3 \
        --use_amber <true/false> \
        --colabfold_model_preset "AlphaFold2-ptm" \
        --use_gpu <true/false> \
        --db_load_mode 0
        -profile <docker/singularity/podman/shifter/charliecloud/conda/institute>
  • The typical command to run colabfold_webserver mode would be:

    nextflow run nf-core/proteinfold \
        --input samplesheet.csv \
        --outdir <OUTDIR> \
        --mode colabfold \
        --colabfold_server webserver \
        --host_url <custom MMSeqs2 API Server URL> \
        --colabfold_db <null (default) | PATH> \
        --num_recycles_colabfold 3 \
        --use_amber <true/false> \
        --colabfold_model_preset "AlphaFold2-ptm" \
        --use_gpu <true/false> \
        -profile <docker/singularity/podman/shifter/charliecloud/conda/institute>

    [!WARNING]

    If you aim to carry out a large amount of predictions using the colabfold_webserver mode, please setup and use your own custom MMSeqs2 API Server. You can find instructions here.

  • The esmfold mode can be run using the command below:

    nextflow run nf-core/proteinfold \
        --input samplesheet.csv \
        --outdir <OUTDIR> \
        --mode esmfold \
        --esmfold_model_preset <monomer/multimer> \
        --esmfold_db <null (default) | PATH> \
        --num_recycles_esmfold 4 \
        --use_gpu <true/false> \
        -profile <docker/singularity/podman/shifter/charliecloud/conda/institute>

Warning

Please provide pipeline parameters via the CLI or Nextflow -params-file option. Custom config files including those provided by the -c Nextflow option can be used to provide any configuration except for parameters; see docs.

For more details and further functionality, please refer to the usage documentation and the parameter documentation.
