thank you that makes sense, I thought I should've looked in Programmer's reference.

Hello

I am looking for documentation on the swc morphology format.
I want to be reminded of what each of the columns in a given file represents.

thank you,
Alexandra

Hello Ted this is again within the context of Depolarization induced suppression of inhibition (DSI). I am implementing a simpler model this time. I want the DSI to start after the pyramidal cell is depolarized and last for 1.8 seconds. I want the amplitude of the current to decay according to the f...

Hello I have a question related to NMODL syntax. I would like the expression for the GABA current to change at the onset of a patch clamp simulation. The patch clamp is not defined in the NMODL file but in my python script. In the mod file, I have set that if my voltage goes beyond a certain value, ...

okay, thank you!

Hello I am using the following model by Aberra 2018 (https://senselab.med.yale.edu/modeldb/ShowModel.cshtml?model=241165). I would like to replace the L23 morphology file with my own morphology file but preserve the synaptic distribution and intrinsic properties of the cell. If I simply replace the ...

thank you Ted, First I would like to say that the syntax: "h.ipulse2(bs.soma(0.5))" gives error "hoc object doesn't have attribute ipulse2" which tells me that I am using the wrong syntax. Should I use "insert" or a different syntax to deliver the pulses to the basket c...

Hello I am using pulsedistrib.zip, to deliver a set of 10 pulses of 1ms approx per pulse. I am having difficulty controlling the Ipulse2 parameters either from my python script or directly from within the mod file. For example, the following syntax doesn't work: iclamp = h.Ipulse2(bs.soma(0.5)) #whe...

Yes, this fixes the problem. :)

Thank you!

thank you Ted, I responded with a private message attaching my mod file.

thank you Ted this works great except that I am facing now an issue holding the potential to the exact voltage defined by the SEClamp. Here are two examples: in the first case the voltage is held at -70 for 1000ms (but in praxis there are transients and the voltage deviates from -70mV) and in the se...

Hello I am trying to do the trivial task of adding a depolarization step during pyramidal cell voltage clamp. The holding potential is at -70mV and after some time I want to depolarize the cell to 0mV for 200ms. I treat this as two separate voltage clamps. However, the following syntax yields a volt...

Hello I have a mod file that computes depolarization induced suppression of inhibition (DSI) which relies on the depolarization of the postsynaptic cell. For that, I need to access the calcium concentration of the postsynaptic cell that would be elevated upon depolarization. If I call"cai"...

Dear Ted I've attempted to correct the code according to your remarks. Here are some answers: The SOLVE statement refers to a non-existent equation block. This is a fatal problem. I now use cnexp which from what I have seen in numerous examples aside from differential equations is also used to solve...

thank you Omar the file takes time to compile using a lot of resources, it looks stuck. The notice: Use of pointer is not thread-safe still appears but I assume I can ignore that for now. Can I share via email the equations I have attempted to convert to a mod file? I don't think I can attach a scre...
