Getting started with molecular modeling software can be overwhelming. Whether you’re a student new to computational chemistry, a researcher venturing into a new type of simulation, or an educator looking for a fast-start guide for your students, there’s a steep…

One of the recurring challenges in molecular modeling is generating plausible intermediate protein conformations between two known states. Whether preparing paths for molecular dynamics simulations or simply aiming to visualize conformational changes, researchers often find themselves lacking tools that strike…

Designing DNA nanostructures in silico is an exciting way to prototype molecular devices before heading to the lab. But one question frequently halts the creative process for many researchers: How can I turn my design into data suitable for simulation?…

When building molecular presentations, showing how a structure fits together or interacts with another is often as much about visual storytelling as it is about science. But a common pain point for many molecular modelers is creating fluid camera movement…

When setting up a molecular simulation or designing a new protein structure, even small conformational anomalies can lead to poor results or simulation instabilities. One of the most common issues? Residues with unfavorable backbone dihedral angles. That’s where the interactive…

Scientific research often relies on software reproducibility. Whether you’re trying to replicate published work, maintain compatibility with existing tools, or avoid retraining a team, there are good reasons molecular modelers sometimes need older versions of software—even in fast-evolving platforms like…

Creating clear and instructive molecular animations can be challenging, especially when you want to highlight vertical structures or transitions—like showing a ligand moving through a channel, traveling along an alpha helix, or simply scanning through layers of a molecular system.…

For molecular modelers, setting up GROMACS can often be a lengthy and complex process involving multiple dependencies, manual compilation, and configuration. If you’ve ever struggled with installing GROMACS or spent hours resolving compatibility issues, you’re not alone 🎯. Fortunately, SAMSON…

When working with biomolecular simulations, especially in large and complex systems, index groups are essential. They define subsets of atoms in your system and can be used during simulation setup, analysis, or when applying constraints or forces. GROMACS automatically creates…
