Extending Molecular Modeling Tools for Your Research Needs

One pain shared by many molecular modelers is the lack of specialized tools tailored to their specific research questions. Sometimes a software platform offers 80% of what’s needed, but the missing 20% can slow down or entirely block progress. SAMSON,…

Filtering Molecular Models by Partial Charge Using NSL

OneAngstrom

When working on large-scale molecular simulations or datasets, it’s often useful to filter and select models based on specific criteria—like partial charge. Whether you’re preparing input for a simulation, cleaning up a library of structures, or simply exploring patterns across…

Cleaning 100 PDBs in One Go: Efficient Batch Protein Preparation with SAMSON

OneAngstrom

Anyone who has worked with protein structures knows the feeling: you download hundreds of PDB files for computational modeling, but before you can even run a simulation or docking, you need to clean them. Hydrogens missing. Water molecules everywhere. Ligands…

Quickly Find Conformations by Atom Count in SAMSON

OneAngstrom

When working with molecular systems that contain a large number of conformations, one recurring challenge is efficiently filtering and selecting conformations that fall within specific structural complexity — for example, based on the number of atoms. This can be especially…

Struggling to Learn Molecular Modeling Tools? SAMSON’s Built-In Tutorials Make It Easier

OneAngstrom

For many molecular modelers, the steep learning curve of new platforms can be a major barrier to getting started. Traditional manuals and video tutorials are often non-interactive and require switching back and forth between the tool and the guide. This…

How Symmetry Detection Can Minimize Simulation Time

OneAngstrom

Running molecular simulations at the scale of full biological assemblies can be time-consuming and computationally intensive. But often, nature provides a shortcut: symmetry. If your system has symmetry, you might not need to simulate the entire structure. Instead, you can…

Getting Started with Geometry Optimization in SAMSON Using the FIRE Minimizer

OneAngstrom

Preparing a molecular model for simulation often involves an essential but sometimes time-consuming step: geometry optimization. When atoms are not in energetically favorable positions, your simulation might diverge or waste computational resources on fixing geometry-related problems. Enter the FIRE Minimizer,…

Struggling With Molecular Modeling Tools? Try Tutorials That Guide You Step by Step

OneAngstrom

One of the biggest hurdles faced by researchers and students new to molecular modeling is learning how to effectively use complex software interfaces and tools. Software like SAMSON can be extremely powerful, but its wide range of features can be…

Crystal Waters in the Way? Here’s How to Remove Just the Right Ones

OneAngstrom

When preparing a molecular system for simulation, one of the recurring challenges is deciding what to keep and what to discard. And if you’ve worked with PDB files, you’ve likely faced the dilemma around crystallographic water molecules. Do you delete…

Did Your Molecular Minimization Actually Work? Here’s What to Check

OneAngstrom

After going through the steps of energy minimization in molecular dynamics, it’s tempting to jump straight to equilibration and production runs. But wait — how do you know your energy minimization was successful? Many molecular modelers overlook this crucial verification…
