Modeling Defects in Diamond Crystals with SAMSON

Crystalline materials in the real world often deviate from their ideal structures. Imperfections such as vacancies, substitutions, or interstitials—collectively known as defects—can dramatically influence material properties like conductivity, strength, and optical behavior. Simulating these defects realistically is essential for researchers…

Too Many Atoms? Create Custom Index Groups for Sanity

Anyone working with molecular dynamics (MD) simulations knows the pain: you’re ready to analyze some subtle motion or apply restraints during your GROMACS run, and the default index groups just won’t cut it. You need something specific — a pocket,…

Quickly Find Molecular Models by Atom Counts in SAMSON

Working with large molecular systems often means navigating through complex structures and disorganized data. Whether you’re analyzing biomolecules, designing nanostructures, or handling materials simulations, you’ve probably faced this challenge: how do I quickly locate specific models or folders based on…

Quickly Select Side Chains Based on Attributes in SAMSON

When working with large molecular structures, isolating specific parts of interest—such as side chains with certain atomic properties—can save significant time. This is especially true if you’re preparing simulations, analyzing interactions, or cleaning up your models. In SAMSON, the Node…
