chem-react-ot — React-OT Transition State Generation
Goal
Generate transition state (TS) structures given reactant and product structures using the React-OT model (Optimal Transport). React-OT is a generative model that predicts TS geometries directly without requiring an initial guess path (like NEB).
Category: chemistry
Environment: react-ot-agent
Key Features
- Generative TS Prediction: Predicts 3D transition state structures from 3D reactants and products.
- Fast Inference: Uses an ODE solver for generation, typically much faster than DFT-based NEB.
- No Path Guess Required: Directly generates the TS structure.
Usage
1. Environment Setup
This skill requires the react-ot-agent conda environment. Ensure it is installed:
# Env: react-ot-agent
cd conda-envs/react-ot-agent
bash install.sh
2. Download Models
Before running the skill for the first time, download the pre-trained model weights:
# activate react-ot-agent first
conda activate react-ot-agent
python conda-envs/react-ot-agent/download_models.py
The checkpoint is saved to ~/.cache/react-ot/checkpoints/sb-pretrained.ckpt.
3. Generate Transition State
Run the generation script with reactant and product files (xyz, cif, pdb, etc. - anything ASE reads).
# Env: react-ot-agent
python .agents/skills/chem-react-ot/scripts/generate_ts.py \
--reactants reactant.xyz \
--products product.xyz \
--output_dir results/ts_search
Arguments:
--reactants: Path to reactant structure file(s). Can be a single file with multiple molecules or a list of files.--products: Path to product structure file(s).--output_dir: Directory to save the generated TS structure (ts_generated.xyz) and trajectory (generation_traj.xyz).--nfe: Number of function evaluations for the ODE solver (default: 10). Higher values might be more accurate but slower.--checkpoint: Path to custom model checkpoint (optional, defaults to downloaded one).
Example
# Env: react-ot-agent
python .agents/skills/chem-react-ot/scripts/generate_ts.py \
--reactants .agents/skills/chem-react-ot/examples/oxadiazole_isomerization/reactant.xyz \
--products .agents/skills/chem-react-ot/examples/oxadiazole_isomerization/product.xyz \
--output_dir .agents/skills/chem-react-ot/examples/oxadiazole_isomerization/output
Constraints
- Environment: All scripts require the
react-ot-agentconda environment. - Input Format: Reactant and product structures must be in any format readable by ASE (XYZ, CIF, PDB, etc.).
- Atom Ordering: Reactant and product structures must have the same number of atoms with consistent atom ordering.
- Model Checkpoint: The pre-trained checkpoint must be downloaded before first use (see step 2).

# `chem-react-ot` — React-OT Transition State Generation
## Goal
Generate transition state (TS) structures given reactant and product structures using the React-OT model (Optimal Transport). React-OT is a generative model that predicts TS geometries directly without requiring an initial guess path (like NEB).
**Category:** `chemistry`
**Environment:** `react-ot-agent`
## Key Features
- **Generative TS Prediction:** Predicts 3D transition state structures from 3D reactants and products.
- **Fast Inference:** Uses an ODE solver for generation, typically much faster than DFT-based NEB.
- **No Path Guess Required:** Directly generates the TS structure.
## Usage
### 1. Environment Setup
This skill requires the `react-ot-agent` conda environment. Ensure it is installed:
```bash
# Env: react-ot-agent
cd conda-envs/react-ot-agent
bash install.sh
```
### 2. Download Models
Before running the skill for the first time, download the pre-trained model weights:
```bash
# activate react-ot-agent first
conda activate react-ot-agent
python conda-envs/react-ot-agent/download_models.py
```
The checkpoint is saved to `~/.cache/react-ot/checkpoints/sb-pretrained.ckpt`.
### 3. Generate Transition State
Run the generation script with reactant and product files (xyz, cif, pdb, etc. - anything ASE reads).
```bash
# Env: react-ot-agent
python .agents/skills/chem-react-ot/scripts/generate_ts.py \
--reactants reactant.xyz \
--products product.xyz \
--output_dir results/ts_search
```
**Arguments:**
- `--reactants`: Path to reactant structure file(s). Can be a single file with multiple molecules or a list of files.
- `--products`: Path to product structure file(s).
- `--output_dir`: Directory to save the generated TS structure (`ts_generated.xyz`) and trajectory (`generation_traj.xyz`).
- `--nfe`: Number of function evaluations for the ODE solver (default: 10). Higher values might be more accurate but slower.
- `--checkpoint`: Path to custom model checkpoint (optional, defaults to downloaded one).
