Making Your Molecular Presentations Repeatable: Exporting Trajectories with Record Path in SAMSON

When preparing molecular animations, a common challenge for modelers is being able to not only display molecular transformations (e.g., docking, conformational changes, molecular motion), but also to preserve these transformations as reproducible trajectories. Whether you’re preparing an educational presentation, documenting…

Bringing Molecules to Life: A Simple Way to Loop Appearances with the Pulse Animation in SAMSON

OneAngstrom

In molecular modeling, clear visual storytelling is often just as important as the molecular data itself—especially when communicating findings or creating educational material. A common challenge modelers face is how to effectively highlight specific molecular structures or dynamics in a…

Making Sense of Node Group Selection in SAMSON

OneAngstrom

In complex molecular models, clarity and control are essential. When working with numerous nodes in a model — atoms, molecules, fragments, and related groups — being able to efficiently select and manipulate specific elements can be a real time-saver. This…

Quickly Filter Molecules by Number of Chains in SAMSON

OneAngstrom

When working with biomolecular models, it’s common to deal with multi-chain systems, including proteins with several subunits or complexes with ligands. But what if you’re trying to pinpoint just the monomeric structures? Or maybe you’re only interested in dimers or…

Getting Your Molecular System to the Right Temperature in GROMACS Wizard

OneAngstrom

One of the most common stumbling blocks for molecular modelers performing simulations with GROMACS is ensuring that their system is properly equilibrated at the right temperature before production runs. Jumping into molecular dynamics without this step can lead to unphysical…

Make Atoms Flash: A Simple Way to Emphasize Molecular Events

OneAngstrom

When presenting molecular mechanisms, one challenge researchers often face is how to draw attention to key events or components without overwhelming the viewer with too much visual information. Whether it’s emphasizing a cofactor binding, a sudden conformational change, or the…

Manually editing molecules without breaking your simulation? IM-UFF makes it possible.

OneAngstrom

One common challenge in molecular modeling is modifying molecular structures on the fly—connecting or breaking bonds—without having to recalculate everything from scratch. Typically, simulations require a fixed topology, and making any structural change leads to restarting your workflow, setting parameters…

Reducing False Positives in Protein Docking with Range Angles in Hex

OneAngstrom

Protein docking can be time-consuming, especially when predictions yield a large number of unlikely conformations. One of the most common frustrations for molecular modelers is spending hours sorting through thousands of docking results only to end up discarding most due…

One Label, Many Insights: Making Your Molecular Measurements Last

OneAngstrom

When performing molecular modeling, there are moments when a single distance or angle carries more meaning than lines of code. Whether you’re comparing bond lengths between minimized geometries, analyzing conformational changes, or just trying to keep track of a torsion…

When Global Doesn’t Fit: Aligning Specific Protein Segments in SAMSON

OneAngstrom

Protein alignments play a crucial role in structure-based molecular design, helping researchers uncover conserved regions, highlight conformational differences between homologs, and guide homology modeling. But what happens when you’re only interested in a specific part of the protein? That’s a…
