When going through a loop of samples, I need to rerun a sample with different condition, e.g. stimulus rate, until the condition is satisfied before moving to the next sample. This is what we discussed in this thread:

[Re-run the model in a previous time segment during a long run](https://brian.discourse.group/t/re-run-the-model-in-a-previous-time-segment-during-a-long-run/296)

I used runtime mode since then. Now trying to use brian2cuda, I might have to make changes directly in the cuda source. Further inputs would be appreciated.
