SaveState.restore() causes various error
Posted: Mon Jul 22, 2019 1:48 pm
I follows a cerebellar granular layer model published by Sudhakar et al. (2017) which available on ModelDB https://senselab.med.yale.edu/ModelDB/s ... del=232023.
I tried to save and restore the state variables with SaveState class, but once insert scripts for it, the model returns errors during psolve(tstop) (segmentation fault (signal 11) on my local laptop with NEURON v. 7.6.2; assertion (signal 6) on the cluster machine with NEURON v. 7.4, assert message is following).
I inserted save/restore scripts between stdinit() and pc1.psolve(tstop) functions in run.hoc as follows.
The model uses VecStim for input mossy fibre layer, so already modified to generate spikes only after t_state (=20 ms) for restoring simulation.
Is there any possible problem? Or if required, where and how can I share my modified codes?
Many thanks

Code: Select all

pc1.set_maxstep(10)
stdinit()
if(statesCond==0){ // newly defined
pc1.psolve(t_state) // t_state = 20, newly defined
print "saving state with SaveState class."
sprint(stateName,"states%02d.dat",pc1.id)
svstate = new SaveState()
svstate.save()
fstate = new File(stateName)
svstate.fwrite(fstate)
fstate.close()
}else{
print "loading state with SaveState class."
sprint(stateName,"states%02d.dat",pc1.id)
svstate = new SaveState()
fstate = new File(stateName)
svstate.fread(fstate)
svstate.restore()
fstate.close()
pc1.barrier()
}
pc1.psolve(tstop) // tstop = 30, modified
