Avoiding Setup Errors: Choosing the Right Input for NVT Equilibration in SAMSON

Before any molecular dynamics simulation can begin, one crucial step stands in the way: preparing the input files properly. For many researchers working with GROMACS in SAMSON, one common source of frustration is figuring out what input the NVT Equilibration…

Selecting Molecular Segments by Atom Counts, Charges and More in SAMSON

OneAngstrom

When working with large molecular systems, filtering specific parts of the model becomes crucial to speed up workflows and improve clarity. For example, you might want to focus only on segments with a large number of atoms or a particular…

Custom Parameters in GROMACS Simulations: What You Can Control (and How)

OneAngstrom

If you’ve ever run molecular dynamics simulations using GROMACS, you’ve likely encountered the long list of options in MDP (Molecular Dynamics Parameters) files. From integrators to thermostats, every choice influences your results, and getting all of them just right isn’t…

Separate Molecular Groups Visually with the Undock Animation in SAMSON

OneAngstrom

When preparing molecular presentations or exploring molecular complexes, molecular modelers often face the challenge of clearly visualizing how different molecular groups interact — or separate. Whether it’s for highlighting binding interactions, presenting docking results, or explaining receptor-ligand dynamics, it helps…

Revealing Molecular Depth: How Ambient Occlusion Enhances Visual Clarity in SAMSON

OneAngstrom

Understanding the three-dimensional structure of molecules is critical in molecular modeling and design. However, even with powerful visualization tools, complex molecular models can sometimes feel surprisingly flat on screen. This visual ambiguity hinders structural interpretation, especially in densely packed biomolecular…

Introducing Crystal Defects into Diamond Structures in SAMSON

OneAngstrom

One of the most intriguing challenges in molecular modeling is understanding how defects impact the properties of a material. Whether you’re a researcher working on semiconductors or a student exploring crystallography for the first time, modeling defects in crystals like…

Transition Path Optimization Without the Headache: Use Paths, Not Conformations

OneAngstrom

When optimizing molecular transition paths, one crucial decision can save you a significant amount of time and computational effort: choosing the right input format. In SAMSON, the P-NEB method allows you to refine ligand unbinding pathways (or any transition between…

Which Water Molecules Should You Keep for Molecular Simulations?

OneAngstrom

When setting up a biomolecular system for simulation, one recurring challenge for molecular modelers is deciding what to do with water molecules already present in crystal structures. Should you remove them all, keep them all, or try to distinguish the…

Quickly Find the Right Molecule Folders Based on Atoms, Charges, and More

OneAngstrom

If you’ve ever worked on complex molecular systems, you’ve probably run into this problem: hundreds or thousands of folders in a project, each one containing various structural models and atom groups. Locating the exact subset of structures you want to…

Fine-tuning Molecular Visuals in SAMSON: A Deep Dive into Rendering Preferences

OneAngstrom

Visual clarity is crucial when studying molecular structures. Whether you’re presenting a molecular mechanism or investigating the details of a ligand-binding site, your visual output must aid — not hinder — understanding. Fortunately, SAMSON offers an extensive set of rendering…
