What are CHI Energy Functions?

The CHI (Carbohydrate Intrinsic) energy functions score oligosaccharide structures based on glycosidic linkage conformations. Glycosidic torsion angles that deviate from the calculated global energy minima are penalized according to the energy curves. The functions were developed by fitting Gaussian equations to the torsional energy profiles of tetrahydropyran-based disaccharide models, which were obtained using quantum mechanical […]

Where did the AMBER Input Configurator go?

We stopped supporting the AMBER Input Configurator because the field of classical dynamics simulations is moving very rapidly, and we were finding it hard to keep up.  That is, the recommended set of inputs, and their inter-relationships, keeps changing, and might differ from one simulation engine to another (e.g., sander vs pmemd).  This is particularly true […]

What molecules can I build using GLYCAM?

Answer in progress…. Please pardon any mess while this page is being built.  In the meantime, perhaps the information will be of use.  If you have questions, please contact us. The tables below list the current capabilities of the GLYCAM-Web parameter sets. Note: these capabilities might differ slightly from those of the point-and-click builder.  They […]
