Constructor & Destructor Documentation

IMP::npctransport::SimulationData::SimulationData ( std::string  prev_output_file,
bool  quick,
std::string  rmf_file_name = std::string(),
std::string  new_output_file = "" 
)
Parameters
[in]prev_output_filename of protobuf file that encapsulates the assignment data for initializing the simulation params and the output statistics file. The output file is assumed to already exist at this point and contain the assignment. If it contains an rmf_conformation or conformation field, it will be used to initialize particle positions, in that priority.
[in]quickif true, perform a very short simulation, typically for calibration or for initial testing
[out]rmf_file_nameRMF file to which simulation trajectory is recorded (if empty, no RMF file is created upon construction)
See Also
set_rmf_file()
Parameters
[in]new_output_filenew protobuf file for subsequent output and statistics If it is "", then prev_output_file is being rewritten (= default).

void IMP::npctransport::SimulationData::initialize_positions_from_rmf ( RMF::FileConstHandle  fh,
int  frame_number = -1 
)

Open the specified RMF file, links it to the hierarchies of this object, and copy the XYZ coordinates from its last frame into the particles of this object.

Note
this method assumes that the hierarchies that are stored in the RMF file was constructed in the same way as the hierarchies within this SimulationData object. The only major difference between the two is assumed to be the coordinates of the various particles. Otherwise, results might be unexpected, and it is not guaranteed that a mismatch would be detected at runtime.
See Also
IMP::rmf::link_hierarchies()
IMP::rmf::load_frame()

The frame number is the frame in the file to use, if, eg, there are several initial frames to use. If it is -1, the last frame is used.

Exceptions
RMF::IOExceptionif couldn't open RMF file, or unsupported file format
void IMP::npctransport::SimulationData::link_rmf_file_handle ( RMF::FileHandle  fh,
bool  is_restraints = true 
)

Exceptions

bool  is_force_restart = false 
)

resets the name of the RMF file that records the simulation. If an old one exists from a previous call with a different name and different restraints settings, then the previous RMF writer is invalidated by this action (closed and flushed). If the Brownian Dynamics object has already been initialized, a new writer with the new name is added as an optimizer state to it instead of the existing one. TODO: make sure the old writer is indeed closed and flushed

Parameters
new_namethe new name of the rmf file
is_save_restraints_to_rmfwhether to save restraints to this rmf file
is_force_resetif true, force reset even if new_name and is_save_restraints_to_rmf are equal to their old values.
void IMP::npctransport::SimulationData::set_sites ( core::ParticleType  t0,
int  n,
double  r,
double  sr 
)

Parameters
