How to Edit Molecular Properties Without Breaking Relationships

One of the recurring challenges when working with complex molecular systems is the precise editing of atomic or structural properties without disrupting the relationships between nodes. For example, what happens if you want to change the position of a group…

Quickly Find the Right Molecular Folders Using NSL in SAMSON

OneAngstrom

When working with complex molecular systems, an increasingly common pain point among modelers is navigating through large data collections to find specific subsets of structures. Whether you’re analyzing protein complexes, supramolecular assemblies, or atomic simulations, you may often need to…

Avoiding Common Pitfalls When Adding Ions to Coarse-Grained Systems in GROMACS Wizard

OneAngstrom

One of the subtle yet critical steps when setting up molecular dynamics (MD) simulations with coarse-grained (CG) models is ion addition. If not handled properly, the system can become unbalanced or lead to non-physical behavior during simulation. Fortunately, the GROMACS…

Editing Molecular Dynamics Parameters in SAMSON Without Breaking Your Workflow

OneAngstrom

Simulation parameters can make or break the success of a molecular dynamics (MD) run. Whether you’re doing energy minimization or running production simulations, getting those .mdp settings just right is essential. But if you’ve ever spent time tweaking GROMACS parameter…

Take Control of Your Molecular Model’s Bonds with UFF in SAMSON

OneAngstrom

One of the most common frustrations molecular modelers face is lack of control over how simulation tools interpret chemical structures. Automatically detected atom types and bond orders are often sufficient, but there are many cases—organometallic systems, delocalized bonding, non-standard valence—where…

Vertical View Adjustments in Molecular Animations Made Easy

OneAngstrom

When preparing molecular animations, clarity of movement is key—especially if you want to communicate what is happening in a dynamic system effectively. One common challenge for molecular modelers is how to move the camera vertically in a scene while keeping…

Why Your SAMSON Extension Isn’t Loading — And How to Fix It

OneAngstrom

Have you ever installed or developed a new SAMSON Extension, only to find that SAMSON refuses to load it at startup? If you’re working in molecular modeling and relying on Extensions for your research or development, this can be frustrating.…

Building Smart: How to Orient Molecular Fragments Precisely in SAMSON

OneAngstrom

For many molecular modelers, a frequent source of frustration is getting that one fragment to align just right. Whether assembling a ligand into a binding pocket or fusing building blocks into nanostructures, orientation matters. A slight misalignment can mean hours…

Let Your Molecules Rock: A Simple Way to Highlight Movement in SAMSON

OneAngstrom

Visualizing molecular motion is one of the most compelling ways to understand complex structural dynamics. Whether you’re working on protein flexibility, ligand binding, or simply preparing an educational presentation, showing how a structure might move can strengthen your message. But…

From SMILES to 3D structures — no scripting needed

OneAngstrom

Converting SMILES strings into 3D molecular models can often be a tedious step in molecular modeling pipelines. Whether for QSAR, docking, or structure-based drug design, modelers frequently need to visualize or prepare 3D conformations from simple line notations. While scripting…
