For molecular modelers studying viral infection mechanisms, visualizing large structural transitions can be challenging. One of the most important examples in recent years is the opening motion of the SARS-CoV-2 spike, a prerequisite for the virus to bind to human…

Designing complex polymers with repeating sequences can be challenging, especially when you need precise control over structure and connectivity. Whether you’re crafting custom scaffolds, developing synthetic chains, or simulating biopolymers, you often run into limitations with traditional modeling tools. This…

Installing complex modeling software is often the first unexpected hurdle for molecular modelers in academic or industrial environments. Administrative restrictions on shared machines or institutional policies can block installations altogether or lead to days of back-and-forth with IT support. If…

When creating molecular animations, it’s common to focus on the dynamics of a specific region of a system — maybe a ligand binding site, an active pocket, or a flexible loop. However, one common frustration is keeping that region consistently…

If you’re working in molecular modeling, you’re probably used to sending around project files via email or generic cloud services. Whether you’re collaborating on a paper or running simulations with worldwide colleagues, this process can become chaotic fast: mismatched versions,…

Preparing a receptor for a molecular docking simulation can sometimes feel more complex than the docking itself. Whether you’re working on a protein-ligand system or trying to simulate docking into DNA or RNA, the setup process can be a source…

When working with complex molecular systems, you sometimes need to optimize just a portion of a molecule—such as a side chain, a loop, or a binding site—without disturbing the rest of the structure. Minimizing the entire molecule can lead to…

Mistakes happen 🧬. Whether you’re exploring a new protein conformation, editing a reaction intermediate, or simply rearranging atoms in your molecular design, it’s easy to misclick and lose a key step. Fortunately, SAMSON offers a dedicated History view feature that…

When working with complex molecular systems, modelers often need to isolate specific groups of atoms to perform targeted operations, run simulations, or build visualizations. One recurring task is selecting heavy atoms — that is, atoms that are not hydrogen. This…

When exploring molecular systems, molecular modelers often reach a turning point: they need to go beyond viewing and start editing atomistic properties. Whether for preparing simulations, constructing variants of a molecule, or cleaning up input data, changing a molecule’s internal…
