When preparing animated molecular presentations, a common challenge researchers face is visualizing how atoms or molecules move across time. Just watching the animation may not give enough insight into the exact path atoms follow. This can be critical, especially when…

Defining custom index groups can often be one of the trickiest steps for molecular modellers when setting up pulling simulations in GROMACS. If you’re performing center-of-mass (COM) pulling, it’s crucial that the pulled and reference groups are properly defined. In…

Protein modeling often runs into a familiar challenge: real-world flexibility clashes with idealized structures. Simulations can be disrupted by residues adopting unfavored conformations, especially in homology models or modified structures. That’s where interactive editing of dihedral angles becomes essential. The…

When preparing protein structures for molecular dynamics simulations, one common issue is dealing with water molecules in crystal structures. Should you keep them all? Delete them all? The reality is more nuanced, especially when some water molecules are functionally important…

When designing new molecules, one recurring challenge is to understand how small chemical changes affect biological activity or interactions. Whether you’re optimizing binding affinity, reducing toxicity, or simply exploring chemical space, one question often arises: what happens if I slightly…

When building or analyzing complex molecular systems, visual clarity can make a critical difference in understanding structure-function relationships. Labels are small visual elements with a big role: they display information that helps researchers quickly identify atoms, residues, functional groups, or…

When communicating complex molecular structures and their behaviors, clarity is key. For molecular modelers, educators, and researchers who need to illustrate subtle dynamic behavior in molecular systems, static images often fall short. But adding realistic motion to a structure can…

Molecular modeling often involves repetitive tasks where writing scripts becomes a necessity—whether to automate selection, manipulate structures, or analyze properties. But what if you could generate those scripts just by describing what you want in plain English? That’s exactly what…

Creating high-quality molecular visualizations can be time-consuming. Colorizing individual residues, selecting rendering styles, tweaking lighting—we’ve all spent too much time on that perfect image. If you’re preparing figures, presentations, or simply trying to better understand a molecular structure, you probably…
