Re: Calling MPI_Abort() from HOC
Hi Michael, The last version of abrt.mod, above, now compiles on 8.2.2. However, it does not abort anything but rather generates a segmentation violation in a test as you had performed (see below).

Re: Calling MPI_Abort() from HOC
Thank you very much, Michael. Unfortunately, abrt.mod did not compile on nrn 8.2.2, the last version available at the NSG WebPortal. Would a backward-compatible fix be possible? Details on the compilation error follow. Best regards, Charles Relevant compilation error on 8.2.2 on OSX: NEURON -- VERSI...

Calling MPI_Abort() from HOC
Hello, I'm wondering how to call MPI_Abort() from HOC, in the context of an MPI-run simulation on UNIX. The aim is to quit all hosts, including the master, without first receiving all returnable pc.working() calls. The following attempt, among others, did not work. Charles system("MPI_Abort(MPI...

Re: Vext and the extracellular mechanism
Hi Ted, I am not sure I was well understood. I hope you do not mind if I clarify. If periaxonal delta represents its radius, then the first layer of the myelin sheath is at a distance delta from the axolemma. Notwithstanding the radius of the myelin sheath (considering it as collapsed and just outsi...

Vext and the extracellular mechanism
I would first like to ask how Vext is calculated at a given node in a stretch of cable (of defined length and diameter) with one layer of extracellular inserted. Is Vext generated from the Im of that node multiplied by its lateral surface area, xraxial and length? Im here would be subtracted by the ...

Re: Problem compiling InterViews on cygwin: recipe for curso
I downloaded nrniv10.ico as instructed from the hg repository. I re-extracted the tar.gz and copied the file into ../src/mswin. A new related error arises, consisting of "icon file `../../src/mswin/nrniv10.ico' does not contain icon data." Please see the relevant terminal output below. Tha...

Re: Problem compiling InterViews on cygwin: recipe for curso
Dr. Hines, I am using the latest repository codes for IV (07.10.2014) and nrn (nrn-7.3.rel-1173). Compilation of IV occurs without a hitch. Configuration of nrn works, but making it does not. I tried a few different nrn configurations and essentially one type of error arises at the make level: the a...

Re: Problem compiling InterViews on cygwin: recipe for curso
Hello Dr. Hines,
I hope you do not mind my "manually" bumping this post.
Perhaps you may suggest me a specific cygwin subpackage I could downgrade to in the meantime, which would allow this problem to be solved?
Thanks!
Charles

Problem compiling InterViews on cygwin: recipe for cursor.lo
Hello, I am having trouble compiling InterViews (iv-18) with cygwin on Windows 8.1. The problem seems related to the recipe for cursor.lo (cursor.cpp) contained in src/lib/IV-Win. Configuration seems to run without a hitch. The problem arises at the make level. Please see below: CCo@CC ~/iv $ ./conf...

Extracellular: one layer
Hello, In NEURON 7.3, inserting extracellular in a given section with only the following parameters defined, xraxial[0], xg[0], xc[0] and e_extracellular leads to a default insertion in the same section of xraxial[1], xg[1] and xc[1] initialized to default values. I would like to implement a strateg...

# quad forms = 0 means praxis returns by itself
Hello,
I would like a clear explanation for the rules by which Praxis "returns by itself" when the user sets the "# quad forms" to 0 in the MulRunFitter[0] Optimize Praxis GUI.

Re: How to use area(x) and L
I created a bunch of segments that comprise a section with Neuroleucida. I import my morphology into NEURON and implement an nseg strategy based on d_lambda... It is the area of a subset of these bunch of segments that I still wish to obtain. I have understood how to use L: if I want the total lengt...

How to use area(x) and L
Hi, Very basic question... still learning how to talk to NEURON... Wondering how to get lengths and areas of segments that are subsections of a section in the oc> prompt. So for example, I wish to know the area of segments 0-5 of a given section that has 100 segments. How would I ask the oc> prompt ...
