MassiveFold

MassiveFold: parallelize protein structure prediction

MassiveFold's design (see schematic below) is optimized for GPU cluster usage. It allows fast computing for massive sampling by automatically splitting a large run of numerous predictions into several jobs. Each of these individual jobs are computed on a single GPU node and their results are then gathered as a single output with each prediction ranked on a global level instead of the level of each individual job.

This automatic splitting is also convenient for massive sampling on a single GPU server to manage jobs priorities.

MassiveFold is only available with the SLURM workload manager (Simple Linux Utility for Resource Management) as it relies heavily on its features (job array, job dependency, etc...).

A run is composed of three steps:

alignment: on CPU, sequence alignments is the first step (can be skipped if alignments are already computed)
structure prediction: on GPU, structure predictions follow the massive sampling principle. The total number of predictions is divided into smaller batches and each of them is distributed on a single GPU. These jobs wait for the alignment job to be over, if the alignments are not provided by the user.
post_treatment: on CPU, it finishes the job by gathering all batches outputs and produces plots with the plots module to visualize the run's performances. This job is executed only once all the structure predictions are over.

Installation

MassiveFold was developed to run massive sampling with AFmassive and ColabFold and relies on them for its installation.

Steps

Retrieve MassiveFold

# clone MassiveFold's repository
git clone https://github.com/GBLille/MassiveFold.git

For AFmassive runs, two additional installation steps are required to use MassiveFold for AFmassive runs:

Download sequence databases
Retrieve the neural network (NN) models parameters

For ColabFold runs, two additional installation steps are required to use MassiveFold for AFmassive runs:

Download sequence databases
Retrieve the neural network (NN) models parameters](https://github.com/GBLille/AFmassive?tab=readme-ov-file#alphafold-neural-network-model-parameters) and move them to a 'params' folder in the sequence databases folder

Install MassiveFold

We use an installation based on conda. The install.sh script we provide installs the conda environments using the environment.yml and mf-colabfold.yml files. One is created for MassiveFold and AFmassive, and another one is created for ColabFold. It also creates the files architecture and set paths according to this architecture in the AFmassive_params.json and/or ColabFold_params.json parameters file.

Help with:

cd MassiveFold
./install.sh -h

Installation with:

./install.sh [--only-envs] || --alphafold-db <AF_DB_PATH> --colabfold-db <CF_DB_PATH> [--no-env]

Options:
  --alphafold-db <AF_DB_PATH>: path to AlphaFold database
  --colabfold-db <CF_DB_PATH>: path to ColabFold database
  --no-env: do not install the environments, only sets up the files and parameters.
    At least one of --alphafold-db or colabfold-db is required with this option.
  --only-envs: only install the environments (other arguments are not used)

This file tree displays the files' architecture after running ./install.sh.

The directory massivefold_runs is created, which contains:

AFmassive_params.json to set the run parameters for AFmassive,
ColabFold_params.json to set the run parameters for ColabFold,
headers' directory, containing the headers that must be created to use MassiveFold. Examples are given for the Jean Zay national CNRS French cluster (ready to use, see the installation on Jean Zay to run MassiveFold directly on Jean Zay),
input which contains the FASTA sequences,
log with the logs of the MassiveFold runs (debug purposes),
output which contains the predictions,
run_massivefold.sh being the script to run MassiveFold

On a GPU cluster:

the administrator only needs to install the environments:

cd MassiveFold
./install.sh --only-envs

the user only needs to install the remaining files:

cd MassiveFold
./install.sh --no-env --alphafold-db <AF_DB_PATH> --colabfold-db <CF_DB_PATH>

Create header files

Refer to Jobfile's header for this installation step.

To run MassiveFold in parallel on your cluster/server, it is required to build custom jobfile headers for each step. They are three and should be named as follows: {step}.slurm (alignment.slurm, jobarray.slurm and post_treatment.slurm). The headers contain the parameters to give to SLURM for the jobs running (#SBATCH parameters). They have to be added in MassiveFold/massivefold_runs/headers/ directory. Depending on your installation it can be another path, this path has to be set in the AFmassive_params.json and/or ColabFold_params.json as jobfile_headers_dir parameter.

Headers for Jean Zay cluster are provided as examples to follow (named example_header_<step>_jeanzay.slurm), to use them, rename each one following the previously mentioned naming convention.

Set custom parameters

Each cluster has its own specifications in parameterizing job files. For flexibility needs, you can add your custom parameters in your headers, and then in the AFmassive_params.json and/or ColabFold_params.json file so that you can dynamically change their values in the json file.

To illustrate these "special needs", here is an example of parameters that can be used on the French national Jean Zay cluster to specify GPU type, time limits or the project on which the hours are used:

Go to AFmassive_params.json and/or ColabFold_params.json location:

cd MassiveFold/massivefold_runs

Modify AFmassive_params.json and/or ColabFold_params.json:

"custom_params":
{
    "jeanzay_gpu": "v100",
    "jeanzay_project": "<project>",
    "jeanzay_account": "<project>@v100",
    "jeanzay_gpu_with_memory": "v100-32g",
    "jeanzay_alignment_time": "05:00:00",
    "jeanzay_jobarray_time": "15:00:00"
}

And specify them in the jobfile headers (such as here for MassiveFold/headers/jobarray.slurm)

#SBATCH --account=$jeanzay_account
#SBATCH -C $jeanzay_gpu_with_memory
#SBATCH --time=$jeanzay_jobarray_time

Jobfile's header

Building

The jobfiles for each step are built by combining the jobfile header that you have to create in MassiveFold/massivefold_runs/headers/ with the jobfile body in massivefold/parallelization/templates/.

Only the headers have to be adapted in function of your computing infrastructure. They contain the parameters to give to SLURM for the job running (#SBATCH parameters). Each of the three headers (alignment, jobarray and post treatment) must be located in the headers directory (see File architecture section).

Their names should be identical to:

alignment.slurm
jobarray.slurm
post_treatment.slurm

The templates work with the parameters provided in AFmassive_params.json and/or ColabFold_params.json file, given as a parameter to the run_massivefold.sh script.
These parameters are substituted in the template job files thanks to the python library string.Template.
Refer to How to add a parameter for parameters substitution.

Requirement: In the jobarray's jobfile header (massivefold_runs/headers/jobarray.slurm) should be stated that it is a job array and the number of tasks in it has to be given. The task number argument is substituted with the $substitute_batch_number parameter.
It should be expressed as:

#SBATCH --array=0-$substitute_batch_number

For example, if there are 45 batches, with 1 batch per task of the job array, the substituted expression will be:

#SBATCH --array=0-44

Add these lines too in the headers, it is necessary to store MassiveFold's log:

In alignment.slurm:

#SBATCH --error=${logs_dir}/${sequence_name}/${run_name}/alignment.log
#SBATCH --output=${logs_dir}/${sequence_name}/${run_name}/alignment.log

In jobarray.slurm:

#SBATCH --error=${logs_dir}/${sequence_name}/${run_name}/jobarray_%a.log
#SBATCH --output=${logs_dir}/${sequence_name}/${run_name}/jobarray_%a.log

In post_treatment.slurm:

#SBATCH --output=${logs_dir}/${sequence_name}/${run_name}/post_treatment.log
#SBATCH --error=${logs_dir}/${sequence_name}/${run_name}/post_treatment.log

We provide headers for the Jean Zay French CNRS national GPU cluster (IDRIS,) that can also be used as examples for your own infrastructure.

How to add a parameter

Add $new_parameter or ${new_parameter} in the template's header where you want its value to be set and in the "custom_params" section of AFmassive_params.json and/or ColabFold_params.json where its value can be specified and modified conveniently for each run.

Example in the json parameters file for Jean Zay headers:

"custom_params":
{
    "jeanzay_account": "project@v100",
    "jeanzay_gpu_with_memory": "v100-32g",
    "jeanzay_jobarray_time": "10:00:00"
}

Where "project" is your 3 letter project with allocated hours on Jean Zay.

These parameters will be substituted in the header where the parameter keys are located:

#SBATCH --account=$jeanzay_account

#SBATCH --error=${logs_dir}/${sequence_name}/${run_name}/jobarray_%a.log
#SBATCH --output=${logs_dir}/${sequence_name}/${run_name}/jobarray_%a.log

#SBATCH --nodes=1
#SBATCH --ntasks-per-node=1
#SBATCH --cpus-per-task=8
#SBATCH --hint=nomultithread
#SBATCH --gpus-per-node=1
#SBATCH --array=0-$substitute_batch_number
#SBATCH --time=$jeanzay_jobarray_time
##SBATCH --qos=qos_gpu-t4               # Uncomment for job requiring more than 20h (max 16 GPUs)
#SBATCH -C $jeanzay_gpu_with_memory     # GPU type+memory

Never use single $ symbol for other uses than parameter/value substitution from the json file.
To use $ inside the template files (bash variables or other uses), use instead $$ as an escape following string.Template documentation.

Installation on Jean Zay

To use it on Jean Zay, the only installation steps are:

git clone https://github.com/GBLille/MassiveFold.git
./install.sh

The same file architecture is built, follow the usage section to use MassiveFold.

And specify the project you want to use in the AFmassive_params.json or ColabFold_params.json, replacing the <project> value by the 3-letters project name.

Hardware recommendations

We recommend a 4 TB fast storage to host the sequence databases for AFmassive and ColabFold. The requirements in RAM depend on the length of the sequence(s) but 128GB should work for the majority of cases, both for AFmassive and ColabFold. A GPU with at least 16 GB RAM is also recommended, knowing that more memory allows to model larger systems.

Usage

Edit the AFmassive_params.json or ColabFold_params.json parameters file (see file architecture).
Set first the parameters of your run in the AFM_run section of the AFmassive_params.json, for instance:

"AFM_run":
{
    "model_preset": "multimer",
    "max_recycles": "20",
    "templates": "true",
    "dropout": "false",
    "dropout_structure_module": "false",
    "dropout_rates_filename": "",
    "stop_recycling_below": "0",
    "max_template_date": "2024-08-31",
    "min_score": "0",
    "max_score": "1",
    "db_preset": "full_dbs",
    "early_stop_tolerance": "0.5",
    "bfd_max_hits": "100000",
    "mgnify_max_hits": "501",
    "uniprot_max_hits": "50000",
    "uniref_max_hits": "10000"
}

or in the ColabFold_params.json file, for instance:

"CF_run":
{
    "model_preset": "multimer",
    "pair_strategy": "greedy",
    "use_dropout": "false",
    "num_recycle": "20",
    "recycle_early_stop_tolerance": "0.5",
    "stop_at_score": "100",
    "disable_cluster_profile": "false"
}

Then you can set the parameters of the custom_params section if necessary and the plots section.

Activate the conda environment, then launch MassiveFold.

conda activate massivefold
./run_massivefold.sh -s <SEQUENCE_PATH> -r <RUN_NAME> -p <NUMBER_OF_PREDICTIONS_PER_MODEL> -f <JSON_PARAMETERS_FILE>

N.B.: on the Jean Zay cluster, load the massivefold module instead of activating the conda environment

Example for AFmassive:

./run_massivefold.sh -s input/H1140.fasta -r afm_default_run -p 5 -f AFmassive_params.json

Example for ColabFold:

./run_massivefold.sh -s input/H1140.fasta -r cf_default_run -p 5 -f ColabFold_params.json -t ColabFold

If the multiple sequence alignments have already been run and are present in the output folder, they won't be computed, but you can force their recomputation with:

./run_massivefold.sh -s input/H1140.fasta -r afm_default_run -p 5 -f AFmassive_params.json -a

Example to only run the alignments with AFmassive (JackHMMer and HHblits):

./run_massivefold.sh -s input/H1140.fasta -r afm_default_run -p 1 -f AFmassive_params.json -o

or with ColabFold(MMseqs2):

./run_massivefold.sh -s input/H1140.fasta -r cf_default_run -p 1 -f ColabFold_params.json -t ColabFold -o

For more help and list of required and facultative parameters, run:

./run_massivefold.sh -h

Here is the help message given by this command:

Usage: ./run_massivefold.sh -s str -r str -p int -f str [-t str] [ -b int | [[-C str | -c] [-w int]] ] [-m str] [-n str] [-a] [-o]
./run_massivefold.sh -h for more details 
  Required arguments:
    -s| --sequence: path of the sequence(s) to infer, should be a 'fasta' file 
    -r| --run: name chosen for the run to organize in outputs.
    -p| --predictions_per_model: number of predictions computed for each neural network model.
    -f| --parameters: json file's path containing the parameters used for this run.

  Facultative arguments:
    -b| --batch_size: (default: 25) number of predictions per batch, should not be higher than -p.
    -C| --calibration_from: path of a previous run to calibrate the batch size from (see --calibrate).
    -w| --wall_time: (default: 20) total time available for calibration computations, unit is hours.
    -m| --msas_precomputed: path to directory that contains computed msas.
    -n| --top_n_models: uses the n neural network models with best ranking confidence from this run's path.
    -j| --jobid: jobid of an alignment job to wait for inference, skips the alignments.

  Facultative options:
    -t| --tool_to_use: (default: 'AFmassive') Use either AFmassive or ColabFold in structure prediction for MassiveFold
    -o| --only_msas: only compute alignments, the first step of MassiveFold
    -c| --calibrate: calibrate --batch_size value. Searches from the previous runs for the same 'fasta' path given
        in --sequence and uses the longest prediction time found to compute the maximal number of predictions per batch.
        This maximal number depends on the total time given by --wall_time.
    -a| --recompute_msas: purges previous alignment step and recomputes msas.

Inference workflow

It launches MassiveFold with the same parameters introduced above but instead of running AFmassive or ColabFold a single time, it divides it into multiple batches.

For the following examples, we assume that --model_preset=multimer as it is the majority of cases to run MassiveFold in parallel.

However, --model_preset=monomer_ptm works too and needs to be adapted accordingly, at least the models to use (if parameter not set as default).

You can decide how the run will be divided by assigning run_massivefold.sh parameters e.g.:

./run_massivefold.sh -s ./input/H1140.fasta -r 1005_preds -p 67 -b 25 -f AFmassive_params.json

The predictions are computed individually for each neural network (NN) model, -p or --predictions_per_model allows to specify the number of predictions desired for each chosen model.
These --predictions_per_model are then divided into batches with a fixed -b or --batch_size to optimize the run in parallel as each batch can be computed on a different GPU, if available.
The last batch of each NN model is generally smaller than the others to match the number of predictions fixed by --predictions_per_model.

N.B.: an interest to use run_massivefold.sh on a single server with a single GPU is to be able to run massive sampling for a structure in low priority, allowing other jobs with higher priority to be run in between.

For example, with -b 25 and -p 67 the predictions are divided into the following batches (separated runs), which are repeated for each NN model:

First batch: --start_prediction=0 and --end_prediction=24
Second batch: --start_prediction=25 and --end_prediction=49
Third batch: --start_prediction=50 and --end_prediction=67

By default (if --models_to_use is not assigned), all NN models are used: with --model_preset=multimer, 15 models in total = 5 neural network models $\times$ 3 AlphaFold2 versions; with --model_preset=monomer_ptm, 5 neural network models are used.

The prediction number per model can be adjusted, here with 67 per model and 15 models, it amounts to 1005 predictions in total divided into 45 batches, these batches can therefore be run in parallel on a GPU cluster infrastructure.

The batch size can also be auto calibrated with the -c or -C parameters if at least one basic run has already been performed. The -c parameter will automatically search in the output folder that corresponds to the input sequence for the longest prediction duration. These options have to be coupled with the -w walltime parameter (it is advised to adapt this walltime value to the one of the job). For instance:

./run_massivefold.sh -s ./input/H1140.fasta -r 1005_preds -p 67 -f AFmassive_params.json -c -w 10

Parameters

Parameters in run_massivefold.sh

In addition to the parameters displayed with -h option, the json parameters file set with -f or --parameters should be organized like the AFmassive_params.json or ColabFold_params.json file.

Parameters in the json file

Each section of AFmassive_params.json or ColabFold_params.json is used for a different purpose.

The massivefold section designates the whole run parameters.

"massivefold": 
{
    "run_massivefold": "run_AFmassive.py",
    "run_massivefold_plots": "../massivefold/massivefold_plots.py",
    "data_dir": "/gpfsdswork/dataset/Alphafold-2024-04",
    "uniref_database": "",
    "jobfile_headers_dir": "./headers",
    "jobfile_templates_dir": "../massivefold/parallelization/templates",
    "output_dir": "./output",
    "logs_dir": "./log",
    "input_dir": "./input",
    "scripts_dir": "../massivefold/parallelization",
    "models_to_use": "",
    "pkl_format": "full"
}

The paths in the section are filled by install.sh but can be changed here if necessary. Headers (jobfile_headers_dir) are specified to setup the run, in order to give the parameters that are required to run the jobs on your cluster/server. Build your own according to the Jobfile's header building section.
models_to_use is the list of NN models to use. To select which NN models are used, separate them with a comma e.g.: "model_3_multimer_v1,model_3_multimer_v3", by default all are used
pkl_format: how to manage pickle files
- ‘full’ to keep the pickle files generated by the inference engine,
- ‘light’ to reduce its size by selecting main components, which are: number of recycles, PAE values, max PAE, plddt scores, ptm scores, iptm scores and ranking confidence values (stored in ./light_pkl directory)
- ‘none’ to remove them
uniref_databse is the parameter to fix the issue described in the Troubleshooting section. You can change specifically uniref30 database path at this location.
If not specified ("uniref_database": ""), the default uniref30 database path is used (same as AlphaFold2 configuration).

The custom_params section is relative to the personalized parameters that you want to add for your own cluster. For instance, for the Jean Zay GPU cluster:

"custom_params": 
{
    "jeanzay_project": "<project>",
    "jeanzay_account": "<project>@v100",
    "jeanzay_gpu_with_memory": "v100-32g",
    "jeanzay_alignment_time": "10:00:00",
    "jeanzay_jobarray_time": "10:00:00"
}

As explained in How to add a parameter, these variables are substituted by their value when the jobfiles are created.

For AFmassive, the AFM_run section gathers all the parameters used by MassiveFold for the run (see AFmassive parameters section). All parameters except --keep_pkl, --models_to_relax, --use_precomputed_msas, --alignment_only, --start_prediction, --end_prediction, --fasta_path and --output_dir are exposed in this section.
You can adapt the parameter values in function of your needs.
The non exposed parameters mentioned before are set internally by the Massivefold's pipeline or in the massivefold section (models_to_use and pkl_format).

"AFM_run":
{
    "model_preset": "multimer",
    "max_recycles": "20",
    "templates": "true",
    "dropout": "false",
    "dropout_structure_module": "false",
    "dropout_rates_filename": "",
    "stop_recycling_below": "0",
    "max_template_date": "2024-08-31",
    "min_score": "0",
    "max_score": "1",
    "db_preset": "full_dbs",
    "early_stop_tolerance": "0.5",
    "bfd_max_hits": "100000",
    "mgnify_max_hits": "501",
    "uniprot_max_hits": "50000",
    "uniref_max_hits": "10000"
}

Lastly, the plots section is used for the MassiveFold plotting module.

"plots":
{
    "MF_plots_top_n_predictions": "10",
    "MF_plots_chosen_plots": "coverage,DM_plddt_PAE,CF_PAEs,score_distribution,recycles"
}

Relaxation

Because the relaxation takes time and resources to compute and that the MassiveFold process splits the predictions in many batches, the “use_gpu_relax” and “models_to_relax” parameters are set to “false” and “none” respectively. Indeed, if the relaxation is activated during the process, it will be run per batches, before the final ranking, resulting in relaxed structures that wouldn't necessarily be the best predictions. Instead, we recommend to use the colabfold_relax program provided in the MassiveFold conda environment and developed by the ColabFold team, once all the predicted structures are produced and ranked. It allows to relax only selected PDB structures.
For help, type:

colabfold_relax -h

Multiple runs gathering

We provide a gather_runs.py script in the massivefold folder that allows to collate the results of several runs. It gathers all the results and ranks them all.

We also provide an extract_scores.py script that allows to extract the scores from pickle files and create rankings (notably useful for interrupted runs).

massivefold_plots: output representation

MassiveFold plotting module can be used on a MassiveFold output to evaluate visually its predictions.

Here is an example of a basic command you can run:

conda activate massivefold
massivefold_plots.py --input_path=<path_to_MF_output> --chosen_plots=DM_plddt_PAE

Required arguments

--input_path: it designates MassiveFold output dir and the directory to store the plots except if you want them in a separate directory (use --output_path for this purpose)
--chosen_plots: plots you want to get. You can give a list of plot names separated by a coma (e.g.: --chosen_plots=coverage,DM_plddt_PAE,CF_PAEs).

Here is the list of available plots:

DM_plddt_PAE: Deepmind's plots for predicted lddt per residue and predicted aligned error matrix
CF_plddts: ColabFold's plot for predicted lddt per residue
CF_PAEs: ColabFold's plot for predicted aligned error of the n best predictions set with --top_n_predictions
coverage: ColabFold's plot for sequence alignment coverage
score_distribution: performs 3 plots that summarize the score's distribution at three levels:
- an histogram of all scores indiscriminately
- a density plot for each neural network model version
- a boxplot for each neural network model
distribution_comparison: ranking confidence distribution comparison between various MassiveFold outputs, typically useful for runs with different sets of parameters on the same input sequence(s).
recycles: ranking confidence during the recycle process (only for multimers and ColabFold monomers)

Facultative arguments

--top_n_predictions: (default 10), number of best predictions to take into account for plotting
--runs_to_compare: names of the runs you want to compare on their distribution, this argument is coupled with --chosen_plots=distribution_comparison

More help with

conda activate massivefold
massivefold_plots.py --help

Troubleshooting

While using AlphaFold2 or AlphaFold2 based software like AFmassive, you can encounter a bug similar to this one in the msas generation:

WARNING: maximum number of residues 32763 exceeded in sequence UniRef100_A0A5E4B6R9_consensus
or
WARNING: maximum number of residues 32763 exceeded in sequence UniRef100_UPI000F443DA9 titin n=1 Tax=Lagenorhynchus obliquidens TaxID=90247 RepID=UPI000F443DA9
It makes the msas unusable and causes any inference on the sequence to crash. This was referenced in a github issue and a fix was provided.
According to this fix, download an updated version of the uniref30 database. To apply this modification to MassiveFold, set the uniref_database parameter in the AFmassive_params.json file to the updated database similarly to this:

"massivefold": 
{
    "run_massivefold": "run_AFmassive.py",
    "run_massivefold_plots": "../massivefold/massivefold_plots.py",
    "data_dir": "/path/to/databases/AlphaFold/",
    "uniref_database": "/path/to/databases/AlphaFold/UniRef30_2023_02_hhsuite/UniRef30_2023_02",
    "jobfile_headers_dir": "./headers",
    "jobfile_templates_dir": "../massivefold/parallelization/templates",
    "output_dir": "./output",
    "logs_dir": "./log",
    "input_dir": "./input",
    "scripts_dir": "../massivefold/parallelization",
    "models_to_use": "",
    "pkl_format": "full"
}
