Amber

For this specific format, the most relevant information is the trajectory file in its NetCDF binary form (.nc), mandatory on all uploads. ioChem-BD won't render such files but keep them inside the platform for its later download.

Settings

This section captures initialization settings like starting time, timestep used, pressure and temperature regulation, etc.

Data source: <module cmlx:templateRef='control'>

Atomic coordinates

After settings, our HTML resume will output a coordinates table with current molecule atoms and its cell dimensions.

For every atom, we will output it's serial number, atom type, coordinates in cartesian and fractional modes, in angstroms.

Information its read from parameter/topology file specification and trajectory restart file. Solvent atoms will be discarded.
