Modeling protein structures often comes down to fine details — a few outlier residues in non-favorable regions of a Ramachandran plot can raise flags during validation or distort simulation outcomes. If you’ve ever wanted a more intuitive, visual way to…

When setting up molecular simulations, one challenge that modelers often face is finding the right balance between accuracy and computational efficiency. Many simulation tasks—especially when working with spherical or flexible macromolecules like proteins—require significant solvent padding to respect periodic boundary…

Molecular modelers often deal with large systems containing hundreds—or even thousands—of molecules. Whether you’re working on a protein complex, a nanomaterial, or a drug candidate database, being able to rapidly sort and filter your molecular structures based on specific criteria…

When it comes to molecular modeling, every minute spent on repetitive setup tasks is a minute not spent on actual research. If you regularly work with small molecules for docking studies or analog generation, you likely face the chore of…

A frequent challenge in molecular modeling is preparing a protein–ligand system for unbinding pathway simulations. Even experienced users often encounter issues with misassigned atoms or poorly defined conformations, which can invalidate simulation results. Fortunately, the Ligand Path Finder app in…

For many molecular modelers, the ability to fine-tune simulations is not just a luxury—it’s a necessity. Whether you’re calibrating a structure for a paper or improving force field accuracy in a custom system, controlling bond characteristics like bond orders can…

As molecular modelers, we all know the frustration of making an irreversible mistake in the middle of a complex modeling session. You’re halfway through building a structure or simulating an interaction, and suddenly, one misclick sends your project spiraling into…

When presenting complex molecular structures or telling molecular design stories, clarity is critical. Whether you’re building educational content, preparing a conference presentation, or designing a supplementary movie for a paper, the ability to draw attention to individual molecular components in…

Custom index groups are a key ingredient in many GROMACS workflows, especially when preparing for advanced analyses like pulling simulations or restraining specific atoms or residues. But when exactly should you add them? If you’re using the GROMACS Wizard in…

Running molecular dynamics simulations on just one structure rarely tells the whole story. Whether you’re exploring flexible molecules or simulating drug binding in different poses, batch simulations can offer broader insights. But if you’ve ever opened a simulation tool and…
