Center-of-mass pulling (COM pulling) is a widely used molecular modeling technique for stretching biomolecules and studying interactions under strain. While powerful, the workflow can quickly become a headache, especially for those unfamiliar with creating pull-ready simulations with all the necessary…

For molecular modelers, mastering a complex software platform is often one of the initial challenges. Whether you are analyzing molecular dynamics, visualizing structures, or designing new molecules, navigating through intricate interfaces and workflows can feel daunting. This is where interactive…

Molecular modelers often face challenges when cleaning and preparing molecular systems for simulations. Excess data—like alternate locations, unnecessary water molecules, unwanted ligands, and monatomic ions—can create confusion and hinder simulation accuracy. Fortunately, the GROMACS Wizard in the SAMSON platform provides…

Energy minimization is one of the most crucial preparatory steps in molecular dynamics simulations. If you’re struggling to stabilize your molecular systems before running simulations, this phase ensures that your structure avoids high-energy contacts, such as steric clashes, and achieves…

Molecular modelers face the critical task of understanding complex molecular systems, and visualization plays a pivotal role in this process. To see molecules clearly, distinguish between depth, or improve visual accuracy, SAMSON offers a highly customizable Rendering preferences panel. Let’s…

Transition paths can reveal crucial insights into molecular motions, essential for understanding complex systems like protein-ligand complexes or molecular dynamics in chemical transformations. However, modeling these paths with physical accuracy is often a challenge. Scientists tend to start with an…

Molecular modelers frequently face challenges when analyzing Potential of Mean Force (PMF) profiles after extensive umbrella-sampling simulations. Translating simulation data into meaningful results can be time-consuming and requires the right tools. To address this need, the GROMACS Wizard in SAMSON…

For molecular modelers, visualizing molecular trajectories is a critical part of understanding conformational changes, reaction mechanisms, or simulation results. However, one challenge often encountered is the need to intuitively examine trajectories in reverse — to analyze how a molecular system…
