I have model neuron that works. I want to see the effect of changing a parameter. For example

create soma
access soma

soma nseg = 1
soma diam = 18.8
soma L = 18.8
soma Ra = 123.0

soma insert hh

objectvar stim
stim = new IClamp(0.5)

stim.del = 100
stim.dur = 100
stim.amp = 0.1

If I was interested in the simple example above and the effect of altering the cytoplasmic resistance I would want to simulate the neuron from Ra = 100 - Ra = 200 in steps of 5.

Is there a way of doing this without having to change save and run NEURON 20 times?
