Hi, this question is similar to the problems discussed previously (
http://www.neuron.yale.edu/phpBB/viewto ... ions#p7789 and
http://www.neuron.yale.edu/phpBB/viewto ... ions#p7757), but I can't figure out how to solve this. I am running Asshad and Narayanan's model (
http://senselab.med.yale.edu/modeldb/Sh ... del=150551). Each synapse includes a mechanism called cal4, basically a calcium buffer. When I run the model with certain (very strong) stimulation protocols, I get the following errror:
Code: Select all
at line 94 in file cal4.mod:
SOLVE state METHOD sparse
Error at section location apical[5](0.5)
Convergence not achieved in maximum number of iterations
/opt/neuron/nrn/x86_64/bin/nrniv: scopmath library error
in heterosynaptic_plasticity.hoc near line 22
run()
^
fadvance()
advance()
step()
continuerun(1.5e+06)
and others
I'd really like to get around this, and I'd be happy to provide further details by email.
