Dear Petia,

Please excuse my late reply to your questions about restoring NEST simulations. For some reason, your mail had disappeared from my computer.

The behaviour you observe is as expected. When storing and then re-loading and continuing the simulation, a number of things will be different in the second part of the simulation:

• Any spikes that were in transit from pre- to postsynaptic neuron are lost.
• Random number generators re-start from a different point then where they stopped.
• Internal properties of neuron models, such as the state of GSL-based ODE integrators for nonlinear neuron models.

There is currently no way to avoid this loss of information.

Best regards,

Hans Ekkehard
