RoseTTAFold

This package contains deep learning models and related scripts to run RoseTTAFold.
This repository is the official implementation of RoseTTAFold: Accurate prediction of protein structures and interactions using a 3-track network.

Installation

1. Clone the package

   git clone https://github.com/RosettaCommons/RoseTTAFold.git
   cd RoseTTAFold

2. Create conda environment using RoseTTAFold-linux.yml file and folding-linux.yml file. The latter is required to run a pyrosetta version only (run_pyrosetta_ver.sh). ```

   create conda environment for RoseTTAFold

   If your NVIDIA driver compatible with cuda11

   conda env create -f RoseTTAFold-linux.yml

   If not (but compatible with cuda10)

   conda env create -f RoseTTAFold-linux-cu101.yml

create conda environment for pyRosetta folding & running DeepAccNet

conda env create -f folding-linux.yml

3. Download network weights (under Rosetta-DL Software license -- please see below)  
While the code is licensed under the MIT License, the trained weights and data for RoseTTAFold are made available for non-commercial use only under the terms of the Rosetta-DL Software license. You can find details at https://files.ipd.uw.edu/pub/RoseTTAFold/Rosetta-DL_LICENSE.txt

[Update Nov/02/2021] It's now including the weights (RF2t.pt) for RoseTTAFold-2track model used for yeast PPI screening. If you want to use it, please re-download weights. The original RoseTTAFold weights are not changed.

wget https://files.ipd.uw.edu/pub/RoseTTAFold/weights.tar.gz tar xfz weights.tar.gz

4. Download and install third-party software.

./install_dependencies.sh

5. Download sequence and structure databases

6. Obtain a [PyRosetta licence](https://els2.comotion.uw.edu/product/pyrosetta) and install the package in the newly created `folding` conda environment ([link](http://www.pyrosetta.org/downloads)).

## Usage

For monomer structure prediction

cd example ../run_[pyrosetta, e2e]_ver.sh input.fa .

For complex modeling

please see README file under example/complex_modeling/README for details.

python network/predict_complex.py -i paired.a3m -o complex -Ls 218 310

For PPI screening using faster 2-track version (example input and output are at example/complex_2track)

python network_2track/predict_msa.py -msa [paired MSA file in a3m format] -npz [output npz file name] -L1 [Length of first chain] e.g. python network_2track/predict_msa.py -msa input.a3m -npz complex.npz -L1 218

## Expected outputs
For the pyrosetta version, user will get five final models having estimated CA rms error at the B-factor column (model/model_[1-5].crderr.pdb).  
For the end-to-end version, there will be a single PDB output having estimated residue-wise CA-lddt at the B-factor column (t000_.e2e.pdb).

## FAQ
1. Segmentation fault while running hhblits/hhsearch  
For easy install, we used a statically compiled version of hhsuite (installed through conda). Currently, we're not sure what exactly causes segmentation fault error in some cases, but we found that it might be resolved if you compile hhsuite from source and use this compiled version instead of conda version. For installation of hhsuite, please see [here](https://github.com/soedinglab/hh-suite).

2. Submitting jobs to computing nodes  
The modeling pipeline provided here (run_pyrosetta_ver.sh/run_e2e_ver.sh) is a kind of guidelines to show how RoseTTAFold works. For more efficient use of computing resources, you might want to modify the provided bash script to submit separate jobs with proper dependencies for each of steps (more cpus/memory for hhblits/hhsearch, using gpus only for running the networks, etc).
