After initial heating and equilibration, the trajectory may be stable for thousands of time points. During this phase of a simulation, you can collect data. Snapshots and CSV files (see Collecting Averages from Simulations on page 85) store conformational and numeric data that you can later use in thermodynamic calculations. 

To create a set of snapshots of any molecular dynamics run, press the Snapshot button of the Molecular Dynamics Options dialog box to bring up the Molecular Dynamics Snapshots dialog box for naming a snapshot file. A snapshot file contains snapshots of the coordinates and velocities of a molecular system along the trajectory. The dialog box allows you to name the file and decide at what frequency to take snapshots. For example, choosing the snapshot period to be two data steps implies that only every other time step is stored in the snapshot file. 

The format of the binary snapshot file is described in the Reference Manual. 

From time to time you will certainly perform test snapshots2 that are only accumulated in the memory of the detector before you start the real business. If everything looks fine - do not store the test image from the detector memory. Instead repeat the snapshot using the command that directly stores the data in a file. Storage from memory will most probably not dump the correct environmental data to the data files - and if afterwards you want to use the data as, e.g., the machine background and you find out that the exposure and the primary beam intensity have not been stored, you may have a problem. 

Click the Snapshots button if you want playback of MolD trajectories (saved in a movie file. avi).
