Hi, apologies if this is the incorrect place for this post. I've been having a bit of trouble with python correctly reading a binary file output by neuron. Neuron records the data as follows: strdef outdir, fprefix outdir = "./data" fprefix = "test" strdef filename objref runfile...

Is there any way to get the current time of the system from within the nrniv window? Something akin to localtime() in C?

I've created a few new ions using ion_style, but it seems that they're not working correctly. // register the new ions with NEURON cltype = ion_register("cl",-1) hco3type = ion_register("hco3",-1) catype = ion_register("ca",2) forall { kstyle = ion_style("k_ion&quo...

I have: // make the shape plot for point process tracking save_window = new Shape() save_window.size(-245.449,315.449,-160,330) for i = 1,Gstim.count(){ save_window.point_mark(Gstim.o(i), 2, "o", 4) } {save_window.view(-245.449, -160, 560.898, 490, 700, 500, 350.4, 304.96)} fast_flush_list...

I was wondering if there is a way to have multiple point processes of the same type displayed on a shape plot of the cell. I know the point process viewer displays a list of PPs, but I was hoping there is some way I could use the existing windows or design my own window to show them as dots on the c...

location_prompt = 0 xmenu("Location of Synapses") xvarlabel(location_string) xradiobutton("Soma", "set_location(0)") xradiobutton("Proximal Dendrite", "set_location(1)") xradiobutton("Middle Dendrite", "set_location(2)") xradiobu...

I was wondering if you can set boundaries on the possible inputs to an xvalue field editor - for example I have location_paired = 0 xvalue("Location of Paired Synapses","location_paired", 1,"procedure()", 1, 1 ) and I want the only possible values to be 0, 1, 2, 3. Alte...

Sorry, I meant to ask if the concept is the same for point processes/distributed mechanisms. That is, to appear as a button in the GUI, a parameter must be declared as a RANGE variable in the NEURON block. I was having some problems with one parameter of a point process appearing in the point proces...

If instead I wanted a particular parameter of a point process or distributed mechanism available to edit in the GUI, would I need something extra?

Using cnexp, derivimplicit and sparse all gave the same error message. I have read through most of Chapter 9 and some of the programmer's reference, but a lot of the instructions about syntactic rules seem to be given with specific examples, and I have not yet seen an example that explains why this ...

In writing a mod file for extracellular chloride management, I get an error message that a) I don't understand the cause of and b) I'm not sure how to fix. I have: PARAMETER { clbath = 140 (mM) :Resting clo concentration fhspace = 350 (angstrom) txfer = 5 (ms) :Time constant of Clo DFree = 2.03 (um2...

Hopefully this is the right place to put this question. I have written mod files for chloride ion management, one for intracellular and one for extracellular management. In the extracellular management file, I have specified parameters in the PARAMETER block (clbath, fhspace, txfer, DFree), all of w...
