Facing Slow Pre-simulation Cleanup? Try FIRE Minimization Instead

When preparing molecular systems for simulations, one of the most common frustrations is dealing with unstable or unrealistic geometries. Whether you’re importing experimental structures, constructing molecules by hand, or assembling biomolecular complexes, chances are that your atomic coordinates aren’t immediately…

Easily Select and Visualize Residues with SAMSON’s Sequence View

OneAngstrom

If you’ve ever struggled with selecting specific residues in a complex biomolecular structure, you’re not alone. Navigating 3D molecular models to highlight or colorize residues—particularly over long sequences or multiple chains—can be time-consuming and error-prone. Fortunately, SAMSON offers an integrated…

Selective Water Deletion for Molecular Simulations: Why and How

OneAngstrom

When setting up molecular dynamics simulations, one common challenge is deciding what to keep and what to remove from crystallographic structures. Crystal water molecules, for instance, can be tightly bound in the active site or loosely attached elsewhere in the…

When Pressures Rise: A Molecular Modeler’s Guide to NPT Equilibration

OneAngstrom

Equilibrating a molecular system under pressure can be one of the more opaque steps for many modelers. After spending time preparing your simulation and stabilizing the temperature under the NVT ensemble, you’re faced with the task of ensuring your system…

Quickly Find Molecular Conformations Based on Atom Count

OneAngstrom

When working with complex molecular systems, researchers and modelers often generate large numbers of conformations — possible arrangements of atoms in 3D space — during simulations and structure exploration. One common challenge is quickly identifying conformations of interest, especially when…

How to Smoothly Play Molecular Trajectories in SAMSON

OneAngstrom

Visualizing molecular dynamics or conformational changes often requires playing through a defined trajectory or a series of saved conformations. But if you’ve ever tried to animate a path manually or synchronize multiple structural transitions, you probably know how frustrating and…

Turning Simulations into Slide Decks: Using the Stop Animation in SAMSON

OneAngstrom

Molecular modelers often spend countless hours creating compelling simulations and animations that showcase molecular dynamics, binding events, or structural rearrangements. But when it comes time to present these simulations in a structured, slide-like format—especially for lectures or reports—it becomes tricky…

Making Molecular Models Appear or Disappear: A Look into Visual Visibility Attributes

OneAngstrom

When working on complex molecular systems, visual clarity is essential. Whether you’re preparing a figure for publication or curating snapshots for a presentation, chances are you’ve had to hide or reveal parts of your molecular model. But which parts should…

Too Many Simulations Running? Here’s How to Monitor Your GROMACS Jobs in SAMSON

OneAngstrom

Running molecular dynamics simulations can often feel like juggling. You launch one equilibration job… then another… and before you know it, you’re wondering what has finished, what is still running, and where the results were saved. If you’re using the…

Revealing the Hidden Depths: A Look at Progressive Clipping in SAMSON

OneAngstrom

Exploring complex molecular structures, such as large proteins or densely packed nanomaterials, often presents a recurring challenge for modelers: internal features get visually buried inside layers of atoms. Rotating and zooming might help, but more often than not, you lose…
