How to Use Conformer Generator
Commercially Available Online Web Server
Use Conformer Generator online for ETKDG conformer generation, energy minimization, and ligand ensemble analysis.
Conformer Generator is a small-molecule conformational sampling workflow built on RDKit. It generates 3D conformers, minimizes them, filters them by relative energy, and clusters the survivors so researchers can inspect a manageable ensemble of low-energy, structurally distinct states.
On Neurosnap, the workflow starts from an Input Molecule and is controlled by Number Conformers and Minimization Method. It is useful for docking preparation, ligand-flexibility analysis, pharmacophore work, and any project where a single 2D structure is not enough to represent the molecule's accessible geometry.
How Conformer Generator Works
The conformer-generation core follows the ETKDG strategy described by Riniker and Landrum, which improves distance-geometry sampling by injecting experimentally informed torsion-angle preferences. After conformer generation, the workflow optionally minimizes each structure with MMFF94, MMFF94s, UFF, or the auto fallback, then removes energetically unfavorable states.
The remaining conformers are compared through an RMSD matrix and clustered with the Butina algorithm so that one low-energy representative can stand in for each structural family. This is a better fit for downstream medicinal-chemistry work than returning dozens of near-duplicate conformers that differ only trivially.
On Neurosnap, the results table highlights conformer identity, cluster membership, energy, and cluster size, while the viewer lets researchers load representative states directly. If a force field fails on a given molecule, switching the minimization method is often the most useful next step.
What is Neurosnap?
Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools. Because many state-of-the-art machine learning systems remain complex to install, configure, and scale, Neurosnap offers a clean, browser-based workspace that removes the burden of infrastructure management, dependency conflicts, and command-line tooling.
Built for biologists, chemists, and cross-disciplinary scientists, the platform enables advanced computational workflows without requiring expertise in software engineering or cloud architecture. Researchers can launch analyses through an intuitive interface, connect programmatically through a comprehensive API, and rely on automated resource management to scale workloads efficiently. By taking care of the underlying compute and operational complexity, Neurosnap allows teams to devote their energy to scientific progress and faster iteration. Security and data protection remain foundational principles, with clear safeguards outlined in our Terms of Use and Privacy Policy to ensure your work stays protected.
Advancing Discovery with Conformer Generator on Neurosnap
Using Conformer Generator on Neurosnap could drastically accelerate ligand conformer ensemble generation and low-energy representative-state selection from a small molecule.
- Chemically plausible sampling: ETKDG-based generation uses experimental torsion preferences to improve the realism of the sampled conformer set.
- Force-field choice:
Minimization Methodlets researchers choose faster or more chemically tailored refinement depending on the molecule class. - Reduced redundancy: Energy filtering and Butina clustering compress a large ensemble into representative structural families.
- Direct inspection: Energies, cluster sizes, and viewer-based conformer loading make it easier to choose states for docking or follow-up modeling.
