One of the most recurring challenges faced by researchers working with coarse-grained (CG) molecular systems is system preparation. When preparing CG systems for molecular dynamics (MD) simulations using GROMACS, minor parameter misconfigurations can easily lead to inaccurate results or unstable…

If you’re working with covalent inhibitors, you probably know that setting up covalent docking studies can be tricky. From ensuring the correct chemical structure of your ligand to modifying protein residues involved in the covalent interaction, every detail impacts your…

If you’ve ever tried to create a molecular animation and found yourself repeatedly frustrated by parts of the molecule moving when you wish they wouldn’t, you’re not alone. Whether you’re demonstrating a docking mechanism, visualizing a conformational change, or assembling…

Computational molecular scientists often face the frustration of simulation errors caused by incorrect or inconsistent inputs—especially during the NVT equilibration step in molecular dynamics workflows. If you’ve ever encountered unexpected results or crashes at this stage, you’re not alone. One…

When preparing molecular animations, one common challenge is controlling the visibility of structures over time—especially when you need molecules or molecular components to appear exactly at a specific point and remain visible afterwards. This is a frequent need when highlighting…

Anyone who has worked with GROMACS has likely run into this issue: you want to analyze a specific part of your system—maybe all alpha helices, or a binding pocket—but the default index groups just don’t cut it. Manually configuring these…

Designing new molecules often involves tweaking known structures – replacing parts of a molecule to generate analogues for screening. This process can be both time-consuming and error-prone when done manually, especially at scale. If you’re working in drug design, materials…

Whether you’re simulating a protein-ligand complex or a large membrane system, defining the right parameters for your molecular dynamics (MD) simulations can be tricky. Even experienced users of GROMACS sometimes overlook critical details when transitioning from equilibration to production MD.…
