bmtk.simulator.bionet.modules.ecp module

class bmtk.simulator.bionet.modules.ecp.EcpMod(tmp_dir, file_name, electrode_positions, contributions_dir=None, cells=None, variable_name='v', electrode_channels=None, cell_bounds=None)

Bases: bmtk.simulator.bionet.modules.sim_module.SimulatorMod

block(sim, block_interval)

This method is called once after every block of time, as specified by the configuration.

Unlike the step method which is called during every time-step, the block method will typically be called only a few times over the entire simulation. The block method is preferable for accessing and saving to the disk, summing up existing data, or simular functionality

Parameters

• sim – Simulation object

• block_interval – The time interval (tstep_start, tstep_end) for which the block is being called on.

finalize(sim)

Call once at the very end of the simulation.

Parameters

sim – Simulation object

initialize(sim)

Will be called once at the beginning of the simulation run, after the network and simulation parameters have all been finalized.

Parameters

sim – Simulation object

step(sim, tstep)

Called on every single time step (dt).

The step method is used for anything that should be recorded or changed continously. dt is determined during the setup, and the sim parameter can be used to access simulation, network and individual cell properties

Parameters

• sim – Simulation object.

• tstep – The decrete time-step
