DCDReporter¶

class openmm.app.dcdreporter.DCDReporter(file, reportInterval, append=False, enforcePeriodicBox=None, atomSubset=None)¶

DCDReporter outputs a series of frames from a Simulation to a DCD file.

To use it, create a DCDReporter, then add it to the Simulation’s list of reporters.

__init__(file, reportInterval, append=False, enforcePeriodicBox=None, atomSubset=None)¶

Create a DCDReporter.

Parameters

file (string) – The file to write to
reportInterval (int) – The interval (in time steps) at which to write frames
append (bool=False) – If True, open an existing DCD file to append to. If False, create a new file.
enforcePeriodicBox (bool) – Specifies whether particle positions should be translated so the center of every molecule lies in the same periodic box. If None (the default), it will automatically decide whether to translate molecules based on whether the system being simulated uses periodic boundary conditions.
atomSubset (list) – Atom indices (zero indexed) of the particles to output. If None (the default), all particles will be output.

Methods

`__init__`(file, reportInterval[, append, …])	Create a DCDReporter.
`describeNextReport`(simulation)	Get information about the next report this object will generate.
`report`(simulation, state)	Generate a report.

describeNextReport(simulation)¶

Get information about the next report this object will generate.

Parameters: simulation (Simulation) – The Simulation to generate a report for
Returns: A dictionary describing the required information for the next report
Return type: dict

report(simulation, state)¶

Generate a report.
