When modeling molecular pathways—like a ligand unbinding from a protein pocket—researchers often face a simple but frustrating problem: how to export atomic coordinates along a simulated path, but only for the atoms of interest (e.g. the ligand or a specific…

When working with molecular models, especially across multiple projects or complex molecular systems, keeping your workspace clean and organized can be a real challenge. Structures, scripts, data files, different conformations—everything can pile up quickly. If you’ve ever struggled with finding…

Communicating complex molecular processes or simulation results often involves building animated presentations. But often, the focus is exclusively on molecular geometry and motion, leaving the background of your presentation static or blank. This can limit clarity when walking an audience…

When building animations of molecular systems, clarity is key. Scientists often need to guide the viewer’s attention by revealing or removing parts of a complex molecular structure at the right moment. But creating these effects manually—especially when working with large…

Before you hit the “Run” button on a molecular dynamics simulation, one seemingly small but critical decision can save you hours of confusion: selecting the correct input structure. If you’re using GROMACS Wizard in SAMSON for an NVT Equilibration run,…

When viewing a molecular system, a list of coordinates or a ball-and-stick representation can get you only so far. Molecular modelers often need to see what matters—secondary structures, surfaces, fields, or density isosurfaces—to understand interactions, identify regions of interest, or…

If you’ve ever needed to prepare more than a handful of protein structures for docking, molecular dynamics, or energy calculations, you’ve probably faced this challenge: dealing with inconsistencies, missing atoms, or unwanted molecules across dozens (or hundreds) of PDB files.…

For molecular modelers dealing with multi-component systems, navigating and organizing complex structures can be time-consuming and error-prone. Whether you’re working with large protein complexes, nucleic acids, or synthetic compounds, keeping control over your molecular hierarchy is key to productivity —…

When working with complex molecular systems, the visual output can quickly become overwhelming. Proteins, ligands, water molecules, and other components are often jumbled together in multiple representations and colors. As a result, getting a clean, informative image of your model…
