Re: recording t

Actually I encountered the same problem and also a bug with using while (t<tstop) {fadvance()}

I sent you an email with some lines of code which give this result.
I use a prerun, maybe eschombu used this, too?

Re: No linear fit of tau possible

I thought about substracting the offset, but never did it. Thanks for the hint!
Ok, this automatically means, linear fit does not work any more if more than one decaying exponential is influencing the voltage trace, as it might be in an active model..

No linear fit of tau possible

Hey there, I am quite new to NEURON and I have a (hopefully) very simple problem since I could reduce the core of it to its simple basis: I have just one cylinder with simple passive properties and I inject a positive current for some time. Actually, I should be able to measure tau from the voltage ...

Re: Why are cell templates so much slower?

Thank you very much for your answer. Actually we also have bigger morphologies, with >2000 nodes, too, but now we use morphologies of developing neurons, so rather small. I tried to create some package to sent to you, however when I finished and tested it, the effect of slowing down with cell templa...

Why are cell templates so much slower?

Hi there, me and colleagues before me, found that if one creates a cell without using a template, any simulation runs much faster (~4 times) than when you declare the very same cell in a template, even if you only use passive mechanisms and only one PointProcess. Why is that? I searched around alot ...
