Exponential overflow error

[maxwellphenderson]

I was having an issue similar to the one mentioned in:

http://www.neuron.yale.edu/phpbb/viewto ... =31&t=2130

I am not doing any parallelization so I think that the issue must be stemming from an overflow in a mod file. I am using simplified exc. and inh. neurons from ModelDB (#3817 http://senselab.med.yale.edu/modeldb/sh ... tex\README). However, when the error message comes up, it doesn't refer to a particular mod file... additionally, the error comes up semi-randomly (if I change stimulus for the network, on certain values an overflow will occur but NOT on others, if the network has 100 neurons vs 1000 neurons, etc etc). Is there a way to find search issues within neuron mod files, or is this more a guess-and-check issue?

First one must be able to reproduce the error. What to do next depends on the nature of the error message; sometimes that is sufficient to identify the cause. If not, it may be useful to run a simulation that stops a few steps before the message is generated, then advance in single steps while monitoring state and assigned variables. If you are able to fix the problem based on these hints, good for you. If not, zip up just enough code (hoc, ses, and mod files only; no dll, .o, or .c files) to reproduce the problem, and email the zip file to

and I'll tell you what I discover.
