Re: Using ions in multiple mechanisms
Without the TABLE lines, the discrepancy increases. I guess that I can't make analogous changes to what was done in the other post ( http://www.neuron.yale.edu/phpBB/viewtopic.php?f=15&t=1246&start=0 ), probably because the inf and tau expressions in the hyperde3 mechanism are not exactly of...

Re: Using ions in multiple mechanisms
Will the revised code find its way into ModelDB? Future users would find that to be a great benefit. Absolutely! My time investment, especially in the time taken for documentation, is really only worth it if I share the product with others. I've gotten through most of the code, rewriting, comparing...

Re: Using ions in multiple mechanisms
For the sake of completeness: I also realized how it was possible that the mechanism contained currents for both the control and the treated model, without applying both currents to each model: Ex: hyperde3.mod (HCN channel) uses the following ions: hyf, hys, hyhtf, hyhts (the other thing that I fin...

Re: Using ions in multiple mechanisms
In this case, it might make sense to define a new ion for the Ca channels that affect the Ca-gated K channels, so it can have its own accumulation mechanism. Yes, they also have many different Ca2+ ions, and as there are some Ca2+ dependent K+ channels, your note likely explains the multiple Ca2+ i...

Using ions in multiple mechanisms
Hello, I have a few questions about using ions in mechanisms. I was looking through the mechanisms in ModelDB #124513 http://senselab.med.yale.edu/modeldb/ShowModel.asp?model=124513 (Santhakumar/Morgan dentate gyrus model). I also emailed the programmers my question, but wanted to get other general ...

Specify which cells get plotted in a Shapeplot?
Hello, I wrote some hoc code that defines 4 unique cells with positions such that they are arranged in a row when I create a Shapeplot. Now I am wondering if I can limit which cells are displayed in a Shapeplot, ideally making a separate Shapeplot for each cell? I'm fine with a solution using hoc, i...

Re: Typo in reference
Something happened to the text in this documentation page: http://www.neuron.yale.edu/neuron/static/docs/refman/obj.html . The last section 'Footnotes; Inheritance and Polymorphism' has a few incomplete sentences that don't seem to directly follow each other: ... A language supports Polymorphism whe...

for (var) stmt example
What about this? P. 114, section 5.6.4: Working with range variables. It gives an example for iterating over each node including 0 and 1, and then a 'variant' that excludes 0 and 1, but the variant is the same as the original syntax:
Thanks,

Compile under Linux - Other options
Hello, I was looking at the 'Compiling NEURON under UNIX/Linux page: http://www.neuron.yale.edu/neuron/download/compile_linux . In the Other Options section, I noticed it doesn't mention compiling with paranrn for parallel NEURON. Though the instructions for paranrn can be found here, http://www.neu...

Re: Course: Using ModelDB Mainen and Sejnowski 1996
The Mainen and Sejinowski, 1996 model has an Na (sodium channel) mechanism, as you can see from looking at the files in that modeldb entry (there is a file called "na.mod"). So that line is for inserting the sodium channel mechanism defined in "na.mod" into all the sections.

Error with pc.allreduce
Hello, I have an issue using pc.allreduce. I'm running code in parallel on my '2-core' Windows Vista machine using Neuron 7.2 installed at the Parallelization Course. Previously, this code worked fine with the following calls for 1 or 2 processors: mpiexec -n 1 /mypath/nrniv -mpi mycode.hoc mpiexec ...

Re: Access attribute of object owned by other host
Are the xyz coords empirical data or can they be generated algorithmically by any host that wants them and knows the gid of the cell? . The latter - algorithmically. Each host made its own copy of the position vector and just looked up any cell's position as necessary. Right now I'm working with a ...

Typo in reference
Hi, I just noticed this typo in the programmer's reference and wasn't sure where to post for it:
The SYNTAX for Entry "x3d" reads "x3d" but it should read "x3d(i)".
Thanks,
Marianne
