The 'continuous' flag of Vector.play()

I have 2 queries related to the 'continuous' flag of Vector's play() function. When we run the following bit of code, we would expect the 'temp' procedure to be called once for every dt. 1) Why is it getting called every dt/2. 2) Why is 'temp' called twice for time values in tVec? Any explanation wo...

How to plot whole cell currents?

I have built a neuron model with around 200 compartments. There are around 80 AMPA synapses spread out across these compartments. While I can plot the AMPA current with respect to time for each synapse, I would like to plot the whole cell AMPA current, ie the sum of currents through all the AMPA syn...

Problem in opening channel builder .ses files

When I tested the channel with a single compartment model, it worked fine. But once I saved it in a session file and tried to load the session file aga...
