Lock In Your Perfect Molecular View

When preparing molecular animations, it’s easy to focus on moving objects—proteins folding, ligands binding, conformational changes. But one often overlooked element is just as important: the virtual camera. If your perspective shifts unexpectedly between frames where no camera path has…

Managing Complex Molecular Structures with SAMSON’s Document View

OneAngstrom

Molecular modeling projects often involve not just atoms and molecules, but hierarchical systems comprising proteins, ligands, solvents, ions, and other components. When working with such complex structures, users frequently struggle with clarity and navigation—especially when tracking changes or analyzing subcomponents.…

Choosing Initial Conformations for Umbrella Sampling Without Headaches

OneAngstrom

Preparing initial conformations for umbrella sampling can be a daunting process for molecular modelers, especially when dealing with long trajectories or custom paths. Selecting appropriate frames that are well-distributed along a reaction coordinate often requires scripting or external processing. Fortunately,…

Getting Unstuck Faster: Interactive Tutorials Built Into SAMSON

OneAngstrom

When modeling complex molecular systems, getting started with a new software platform can be a challenge. You open the application, browse through menus, and might find yourself wondering: Where do I even begin? If you’ve recently installed SAMSON, the integrative…

A Cleaner Way to Navigate Complex Biomolecules: Introducing the Sequence View in SAMSON

OneAngstrom

When dealing with large biomolecular systems like proteins, DNA, or RNA, molecular modelers often face a persistent challenge: navigating and selecting specific parts within increasingly complex structures. Whether you’re adjusting specific residues, analyzing subunits, or customizing visual representations, finding your…

Making Label Selection Easier in Molecular Models with NSL

OneAngstrom

When working on large molecular systems, simplicity and speed are key. One common challenge among molecular modelers is quickly pinpointing the right label nodes—especially when scenes contain complex visual elements and nested structures. Whether you’re highlighting reaction intermediates or flagging…

Declutter Your Molecular Workspace: Customizing the SAMSON Interface

OneAngstrom

One of the most overlooked obstacles in molecular modeling is having to work in a cluttered or rigid software interface. As your projects grow in complexity, productivity often takes a hit—not because of a lack of features, but because finding…

Quickly Filter Conformations by Atom Count in SAMSON

OneAngstrom

When working with complex molecular systems in SAMSON, molecular modelers often deal with large sets of conformations. These may include snapshots from simulations, different poses from docking, or generated conformational ensembles. However, identifying conformations that meet specific structural criteria—like having…

When a Cube Isn’t the Best Fit: Choosing Space-Filling Unit Cells for Molecular Simulations

OneAngstrom

When preparing a molecular dynamics simulation, one often-overlooked but important decision is the shape of the unit cell used for applying periodic boundary conditions. This decision can impact both the accuracy and performance of your simulation. If you’ve ever wondered…

Avoiding Common Mistakes When Choosing MD Parameters in GROMACS Wizard

OneAngstrom

Deciding on parameters for a production molecular dynamics (MD) simulation can be one of the most deceptively time-consuming tasks in computational molecular modeling. The settings you choose—such as the number of steps, the time step size, and coupling constants—can significantly…
