Hi,

We've discovered the following problem in restoring network simulation: if the simulation stops for some reason restoring it form the network status kept in files does not yield the same results as in case when the simulation was not interrupted and finishes normally.

In our experiment we run a script twice as follows:

1. Create a network and simulate for some period of time.

2. Record the current network status in terms of connections and membrane potentials and store them in files at the end of script.

3. End the script

4. Start the script again restoring the network structure from files.

5. Run simulation till the end of desired time.

The spiking activity of the network is different if we run simulation without interruption or if we run it in the manner described here: https://nest-simulator.readthedocs.io/en/stable/auto_examples/store_restore_network.html

i.e. if we run a script with following steps:

1. Run simulation for some time.

2. Get connections and membrane potentials

3. Reset kernel

4. Create again the network

5. Simulate till the end of desired time.

Please help to resolve the problem.

Best,
