class htmd.membranebuilder.pdbreporter.PDBReporter(file, reportInterval, enforcePeriodicBox=True)#

Bases: object

PDBReporter outputs a series of frames from a Simulation to a PDB file.

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

describeNextReport(simulation)#

Get information about the next report this object will generate.

Parameters:: simulation (Simulation) – The Simulation to generate a report for
Returns:: A five element tuple. The first element is the number of steps until the next report. The remaining elements specify whether that report will require positions, velocities, forces, and energies respectively.
Return type:: tuple

report(simulation, _)#

Generate a report.

Parameters:

simulation (Simulation) – The Simulation to generate a report for
_ (State) – The current state of the simulation

class htmd.membranebuilder.pdbreporter.PDBxReporter(file, reportInterval, enforcePeriodicBox=True)#

Bases: PDBReporter

PDBxReporter outputs a series of frames from a Simulation to a PDBx/mmCIF file.

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

report(simulation, _)#

Generate a report.

Parameters:

simulation (Simulation) – The Simulation to generate a report for
_ (State) – The current state of the simulation
