In my model I want to inject a current of 40000 nA (0.04 mA) for 0.05 ms. I am delivering it as a single stimulus (using IClamp) or as a stimulus train (using the method which is given as answer to the following question in FAQ section "I just want a current clamp that will deliver a sequence of current pulses at regular intervals. Vector play seems like overkill for this" ). In both cases NEURON says "exp(999.222) out of range, returning exp(700)". I know that exp(900) is Inf, but where this exp term is involved ? Is it not possible to inject such a high value of current ?
I tried converting the unit of current stimulus to mA in iPulse3.mod. But NEURON cries unit descrepancy, and throws the following error.
Can someone help me on this ?The previous primary expression with units: 0.001 coul/sec
is missing a conversion factor and should read:
(1e+06)*()
at line 46 in file iPulse.mod
ival = amp<<ERROR>>
