Speeding Up Molecular Library Design with SAMSON’s Fragment Replacement Tool

Designing new molecules often involves tweaking known structures – replacing parts of a molecule to generate analogues for screening. This process can be both time-consuming and error-prone when done manually, especially at scale. If you’re working in drug design, materials…

Common Mistakes When Setting GROMACS Simulation Parameters (and How to Avoid Them)

OneAngstrom

Whether you’re simulating a protein-ligand complex or a large membrane system, defining the right parameters for your molecular dynamics (MD) simulations can be tricky. Even experienced users of GROMACS sometimes overlook critical details when transitioning from equilibration to production MD.…

Filtering Molecular Segments by Number of Residues in SAMSON

OneAngstrom

If you’re building or analyzing large biomolecular systems in SAMSON, chances are you’ve run into situations where you need to quickly identify or isolate segments based on their structural properties. One common challenge is filtering segments by the number of…

Creating Multiple Protein Replicas in SAMSON without Losing Your Mind

OneAngstrom

Preparing systems with multiple protein replicas is a common need in coarse-grained molecular modeling, especially when studying self-assembly or concentration effects. Yet, what seems like a simple task—duplicating a single protein structure several times—can quickly turn into a frustrating experience…

Clarifying Complex Transitions: Hiding Molecular Structures with SAMSON

OneAngstrom

When creating molecular animations, clarity is everything. Whether you’re illustrating mechanisms of action, molecular interactions, or structural rearrangements, guiding your audience’s focus without overloading the scene is a challenge. One effective way to enhance focus is by hiding parts of…

Running SAMSON Without Admin Rights: A Guide for Molecular Modelers

OneAngstrom

For many researchers and students working in universities, biotech companies, or public labs, installing software without administrator rights can be surprisingly difficult. IT policies, locked systems, and resource approval cycles often get in the way—preventing scientists from quickly testing or…

Making Molecules Disappear Gracefully in SAMSON

OneAngstrom

Visualizing molecular transformations can be challenging, especially when you want to guide your audience’s attention through a clear and digestible path. One common request from molecular modelers and presenters is the ability to create clean transitions between different components of…

Saving Molecular Flexibility: How to Export Conformations and Trajectories in SAMSON

OneAngstrom

One of the challenges many molecular modelers face when analyzing the flexibility and dynamics of biomolecules is keeping track of interesting conformations or motion trajectories. Whether you’re preparing a figure for publication, comparing several states of your molecule, or simply…

A Simple Way to Surround Your Protein with Lipids in SAMSON

OneAngstrom

Adding lipid layers around proteins is a common requirement in molecular modeling, especially for studying membrane proteins and receptor dynamics. But the process often feels unintuitive, involving multiple software tools, scripts, and tedious alignment steps. If you’ve ever struggled to…

When (and Why) to Minimize Ligands Before Docking

OneAngstrom

One common hurdle in molecular docking is dealing with ligand libraries pulled from various sources. Some are fully prepared, others are in 2D or have improper geometries. If docking fails or gives poor results, it’s easy to blame the algorithm…
