One of the critical aspects of molecular modeling with periodic boundary conditions is ensuring compliance with the minimum image rule. If this principle is overlooked during system setup, simulations may produce erroneous results due to artificial interactions of molecules with…

When working on molecular modeling, understanding the spatial organization of atoms is fundamental. If you’ve ever wondered how to analyze the local packing of molecules, solvation structures, or interaction distances between atomic groups, the Radial Distribution Function (RDF) can provide…

For molecular modelers working on protein-ligand systems, ligand parametrization is often a challenging step. Whether it’s navigating the compatibility of force fields or ensuring the ligand structure is accurate, mistakes during this process can lead to ineffective simulations. Here, we…

For molecular modelers, visualizing and presenting complex molecular assemblies in an easily understandable way can be a challenge. Effective animations can significantly help in communicating ideas, but getting structures aligned realistically and dynamically is often a time-consuming task. This is…

Molecular simulation is a powerful tool in understanding biological systems, but its effectiveness begins with proper preparation. One of the most common challenges molecular modelers face is simulation errors caused by poorly prepared molecular systems. Preparing a clean starting structure…

Protein docking is a crucial component of molecular modeling, but one of the major pains faced by molecular modelers lies in the preparation of protein systems. Errors in this step can lead to inaccurate docking results, which can derail research…

For molecular modelers, one of the toughest challenges is experimenting with molecular interactions dynamically. What if you could manipulate atoms in real-time as your system responds to every move? Enter SAMSON’s interactive simulators – a powerful tool to let you…

For molecular modelers, getting the simulation box dimensions correct in GROMACS is critical, and errors here can compromise results down the line, especially when working on center-of-mass (COM) pulling simulations. This blog post focuses on setting up a suitable simulation…

Molecular modeling requires precision, and when working with complex molecular structures in SAMSON, managing attributes for selected nodes can feel overwhelming. If you’ve ever struggled to quickly locate specific attributes amidst a sea of data, the Inspector’s Filtering tool can…
