Thanks,
Then I guess neuron will have to be started without the GUI, right? but nrniv doesn't read additional mechanisms present in the directory as nrngui does, so what would be the correct way of starting the process?

Hi, I've set up a Linux machine to be used exclusively for running simulations. The idea is to run neuron both locally and remotely, depending on the kind of simulation. In the remote case (and maybe in the local case too), I would like to start a simulation and be able to close the session (to shut...

Well, it compiled but didn't work properly. There were more errors in the .c file that permitted compilation but made a completely different mechanism. To illustrate it better, I experimented with a simpler model; 4 states in a line. In the 'non-array' version, the DERIVATIVE block is DERIVATIVE sta...

Doh!
Now it works. Thanks a lot!!

Almost, almost there!! The DERIVATIVE block is: DERIVATIVE states { mh'[0] = (-3*am-ah)*mh[0] + bm*mh[1] + bh*mh[4] mh'[1] = (-2*am-bm-ah)*mh[1] + 3*am*mh[0] + 2*bm*mh[2] + bh*mh[5] mh'[2] = (-am-2*bm-ah)*mh[2] + 2*am*mh[1] + 3*bm*mh[3] + bh*mh[6] mh'[3] = (-3*bm-ah)*mh[3] + am*mh[2] + bh*mh[7] mh'[...

Thanks a lot, Mike.
I'll give it a try. I still can use a Linux machine, though ;)

Thanks! There was indeed an error in the mod file. I fixed it, and now both mknrndll and nocmodl create a non-empty .c file. I see where and how to fix the c file it but I'm having another problem: unlike nrnivmodl, mknrndll does overwrites the .c file. It doesn't seem to care about file dates, it s...

Hi,

I'm trying to the same as sec6. When compiling, after mknrndll stops there is a "mymodfile.c" file left but it is empty. Where am I supposed to edit and fix the c code?
PS: I'm working in Windows. Please don't tell me that fixing the c code is only possible under Linux.

Regards.

Yes!! .compute(freq,1) did it.
I don't know how to try the code you posted, do I have to compile the whole program? Or there is a way to compile just those two files?

Thanks a lot!

Yes, it happens both with 7.0 and 7.1

Hi, I want to monitor the impedance of the model neuron while simulation is running, let's say every 50 ms. So I made a script that advances 50 ms, pauses the simulations and recalculates an impedance object that is inserted. However, starting from Neuron 7.0 I found out that I can't do this any lon...

Good advice. Thanks again.

Great! I don't know why I assumed that the previous flag=1 event was deleted or something by the new one. So now I understand that I was creating and creating events at each voltage change. The fixed (and probably final) code looks like this: TITLE Mock stochastic voltage-dependent sodium channel : ...

A flag=2 event sends a flag=1 event. And a flag=1 event sends a flag=1 event. Right, but all events are sent with a proper next_ev time delay, isn't it? This is what seems not to be working when WATCH is present. Is there a way to monitor event generation, delays, and arrivals while the simulation ...

I believe the problem is that every time the voltage changes from vlast by more than 5mV you start a whole new series of flag=1 streams that never ends. And why is that? I can't see it in the code. Did I miss something in the way WATCH works? This is occurring with the fixed step method as well but...
