Okay, thanks for the detailed explanation. Currently I call the xopen within the init function, so it is executing during the creation of each instance, in the context of the instance. This works fine for me right now. I will think of whether I can rearrange things so as to call it at the top level ...

Great, thanks! I didn't realize the difference in context of these two functions either. I just tried xopen in my actual code and it is working fine now.

Hello, I have a template that defines some variables within it. Within the template, I want to load a hoc file that references those variables (about 160 lines long). How can I do this? Here is a very simple example of what I want to do: 1. Load in the template definition in this file called testcla...

Will there be an updated NEURON bibliography soon? I noticed this one is from January, 2012: http://www.neuron.yale.edu/neuron/stati ... ednrn.html

Michael, thanks for your quick help with this! I appreciate your work as always. It's such a relief to have a working NEURON again!

I ran into trouble using mknrndll with the new version. If I just compile a c++ program separately from NEURON in my stand-alone Cygwin installation using g++, it works fine. However, if I try to use mknrndll (either in the mintty bash or the separate mknrndll tool), I get this error: bash-4.1$ mknr...

Great, I installed this new version and it fixed the problem. Thank you!

Hello, there is an issue with older versions of Cygwin and Windows 8.1. They have fixed it in their latest Cygwin version. I received the error after updating my computer to Windows 8.1, until I updated my Cygwin as well. Now I no longer receive the error except when I open NEURON using Cygwin. I do...

Hello, we have come across a few bugs in the ion channels of the Santhakumar/Morgan model on on ModelDB ( http://senselab.med.yale.edu/modeldb/ShowModel.asp?model=124513 ). We are addressing these in a future model version. As the cell models used in this model were fit to experimental data and thei...

Hi pascal, I just now noticed this post, sorry. The ModelDB version is meant to be run from the GUI. If you start NEURON, then load the 50knet.hoc file from within the NEURON GUI, this error will not occur. Let me know if you want a version of this code that runs independently from the GUI.

Okay, thanks, I appreciate it! Also, if there's anything you want me to try on my machine, let me know. I don't mind editing files and trying the compile again, if you have some ideas of what edits might work.

Correct, I was using the standard 7.3 code. I had assumed my environment was missing something and didn't think to try a newer version, sorry. I now pulled in the latest code from Mercurial and ran build.sh on version (19:44d6ec5724f4), and I'm not sure if the warnings it gave can be ignored, so I t...

Hello, I'm following the directions for compiling the standard NEURON 7.3 dist on my Windows 8 64-bit machine using 64-bit Cygwin (http://neuron.yale.edu/neuron/download/compile_mswin). I get errors during make. Not sure if I am missing some Cygwin packages; here are some relevant ones I have instal...

So somehow an actual "cygdrive" folder got created in my C: drive, and it partially replicated the directory tree under my C: drive. The NEURON GUI would only look into that cygdrive folder, and couldn't look higher than its level. But it is fixed now. There was a newer version of Cygwin a...

I used nrn-7.3.i686-pc-cygwin-setup However, I've just realized that this problem is definitely broader than NEURON. Within MATLAB, path completion only works if I use the Windows path form (C:\...). If I use the Cygwin form of /cygdrive/c/..., then only one model subdirectory is available (the same...
