virtual	~Structure ()=default

uint64_t	frameCount () const
	Get the number of frames.

uint64_t	framePosition () const
	Get the current frame index.

bool	framePositionsLoaded () const

Detailed Description

Read CONFIG files.

Remarks

The file structure is:

A title line [string].
A meta data line.
- levcfg [integer] 0 = positions, 1 = positions and velocities, 2 = positions, velocities, and forces.
- imcon [integer] boundary type.
- megatm [integer] atom count.
A set of n*(1+levcfg) recrods.
- positions [float, float, float]
- velocities [float, float, float], if levcfg > 0
- forces [float, float, float], if levcfg > 1

A trajectory is the HISTORY file which contains more information.

Constructor & Destructor Documentation

inline

Construct a new CONFIG object to read from path.

Parameters
